Note: This HID Kit is for the replacement of two headlamp bulbs. The kit contains two HID bulbs and two ballasts
What is an H4 Stealth HID Kit?
An H4 HID kit is simply a kit that allows you to upgrade your existing H4 halogen bulbs to Xenon HID (High Intensity Discharge) technology seen on many newer cars. The benefit of upgrading to HID is the huge amount of extra light you get compared to the yellow candle like light that a standard H4 halogen bulb will emit.
How much extra light do I get from a 55W HID Kit?
This will differ somewhat from car to car, however the 55W Stealth HID Kits will give approximately 400% more light on the road. This is a massive improvement which will transform your night time driving experience. Not only are these brighter than halogen bulbs, you are getting more light than you would get from an OEM factory fit system! Hazards, road markings, corners, signs and anything else you need to see will be far more visible, increasing road safety significantly.
Will this kit upgrade both dipped and main beam?
As you may be aware a standard H4 halogen bulb has two filaments. This means it provides the light for both your dipped (low) beam and your main (high) beam. The H4 Stealth Kits are specifically designed to ensure both these functions are maintained and you get the advantages of HID across both dipped and main beam. This is done with a solenoid system built into the bulb that shifts the light between main and dipped beam function as required.
What's so good about the H4 Stealth HID Kit?
This is a fair question as there are a large number of HID kits available on the market, especially on the "cheap and cheerful" marketplaces that we all know and love! However, despite first appearances, all HID kits are not built the same!
Here at HIDS4U, we are not just a reseller. We do extensive testing and product development on our HID conversion kits. We ensure only the best quality components are used to give you the performance you are expecting.
With our products you can expect the following:
Correct beam pattern due to perfectly aligned light source in our bulbs.
Consistent bright light due to the quality of the bulbs and ballasts in perfect combination.
No error messages on 99% of vehicles due to the advanced CANBus compatibility systems developed for our ballasts.
No radio interference due to the EMF suppression technology.
No damage to other vehicle components (like the wiper motor) due to surge protection technology.
Slim and stylish ballast to fit in even the tightest of spaces and to look good while it's there!
2 year warranty on all parts as we stand behind our product quality.
What colour H4 HID bulbs can I have?
We offer 3 different colour temperatures depending on your preference. The choice is largely between maximum light output and colour. Let's run through the options:
5000K - The most popular due to them being the brightest of the three. You get a much whiter light than a halogen bulb, but without the blue tint you see with higher K rated bulbs.
6000K - A close second in popularity, only slightly less bright than the 5000K bulbs, but these also come with the added blue tint for that stylish Xenon look.
Do I need a mechanic to fit an HID Kit?
In a word, no! These kits are provided on a DIY plug and play basis. The H4 HID bulbs are a direct replacement for your existing H4 halogens and you then simply connect the bulb cables to the ballast using the plug and play connectors. Often our Stealth ballasts will fit inside the headlight unit, but in the case where you have little room within the unit, you can mount the ballasts in the engine bay. This will require you to drill a small hole in your dust cover to allow the bulb and ballast cables to connect.
Our instructions are written by ourselves in an easy to follow, step by step process and is in proper English. We are also on hand to assist with any queries or issues you have to ensure you are up and running with these as soon as possible.
Is a 55W HID Kit my only option?
The HIDS4U Stealth kits come in two different power ratings, these 55W kits and also a 35W version. The difference is simply the brightness. The H4 35W Stealth HID kits will give up to 300% more light compared to a halogen, whereas these 55W kits are rated at 400% brighter. Most vehicles will be fine with either so it's entirely up to you which one you go for. However some modern vehicles do not like the startup current required to power these 55W kits up. In these cases we recommend using a relay harness to bypass the core vehicle systems, or simply use a 35W kit instead.

Bulbs are excellent. Fitted to a 13 plate Caddy, made a huge difference.
Advantages: Much much better than previous bulbs.
Disadvantages: Trying to find somewhere to neatly secure all the associated cables, junction boxes etc was a real hassle.

The kit itself is really well built and the quality seems good. Installation on W124 headlights require to pass the cables through the seal of the cover, and it's not clear how this will affect the wires on the long term.
However, even if I called the shop and asked if they were ok for MOT and for the road and had been told that they advice to reinstall the original light bulbs for MOT, just to be on the safe side, and they are legal, after some further research (my fault, I should have looked earlier) it turns out that HID conversion kits are, generally, cause for MOT failure if used in cars registered after 1986 and not road legal if used in headlights not made for xenon lamps. See further details from Gov.uk website in the "disadvantage". I'll keep the kit as it has been opened, but I can't recommend it, at least for an old car.
Advantages: Nice, bright light. Good building quality.
Disadvantages: MOT won't pass:

Class 3,4,5 and 7 vehicles
For class 3,4,5 and 7 vehicles, the defect ‘Light source and lamp not compatible’ only applies to vehicles first used on or after 1 April 1986.
Should a vehicle be presented for an MOT test with conversions before 1 April 1986 they must not be failed with immediate effect.
Vehicles presented with converted halogen headlamp units first used on or after 1 April 1986 will continue to be failed.
Generally not road legal:

HID headlamp unit requirements
Therefore a HID headlamp unit sold in the aftermarket should:
be type approved to ECE Regulation 98 as a component
when fitted to the vehicle should enable ECE Regulation 48 to be complied with (although no government inspection will take place)
comply with RVLR as far as “use” is concerned
In practice this means:
the headlamp unit (outer lens, reflector, bulb) shall be type approved to ECE 98 and be “e-marked” to demonstrate this. That can only be done by the headlamp supplier - Hella, Valeo, etc - who must test the headlamp in an independent laboratory
once fitted to the vehicle it must have headlamp cleaning and self-levelling (which can be for the headlamp or can be in the vehicle suspension - some expensive estate cars have “self-levelling suspension” and that is adequate). Also the dipped beam must stay on with the main beam
the headlamp must be maintained in good working order, kept clean, and aligned/adjusted correctly in the same way as any other headlamp
Under the Road Traffic Act 1988 it is an offence to supply, fit or use vehicle parts which are not legal.
In summary: it is not permitted to convert an existing halogen headlamp unit for use with HID bulbs. The entire headlamp unit must be replaced with one designed and approved for use with HID bulbs and it must be installed in accordance with the rules stated above.

These are proper bright and so far impressed I now can see whats in front off me from a distance when driving at night. Skoda fabia standard bulbs are S%IT dipped beam. Communication was excellent via e mail and response time was same day answer. My first order i had choose a single headlight unit and I knew it was wrong as H4 came instead of the H7 so reordered and clicked twin h/L unit and picked next day delivery and they were there next day, Excellent customer service and the returns of the H4 wasn't a problem. Thank's guy's
Advantages: Luv driving at night again being able to see people who are dressed in dark cloths crossing dual carriage and not seeing them to the last few seconds can be scary yet another great move from local council having the road lit up at night was great but a few yr back they decided to drop a lot of the lights and the handful they had left have never been switched on so it pitch black.
Can easily be installed by yourself defo best read manual when you get them helped me alot the diagrams
Disadvantages: were the clips for the new bulbs and skoda not leaving you much room

I've had a few HID kits in my life, from the cheap chinese ebay knock offs to the premium kits such as this. But this kit has to be the worse of them all. The kit lasted only 3 months before one blew. So disappointed to have spent so much on this premium kit to it not even outlast the cheap versions as mentioned above.

First class product, and even better customer service.
I never normally bother to leave feedback but I contacted hids twice while fitting these products to ask silly questions and they answered the phone very quickly and were exstreamly helpful and very good.
I would strongly recommend this company to any of my friends and family.

This is the second set.of these I have bought, fitted them in 15-20 minutes now I know what I'm doing, speed, service and product are are still excellent. The light is bright and white (H4 5000k) exactly what I need to help me see on those dark nights.

I had heard good things about these light conversion kits and ecidied to give one a try. It took about 30 minutes to fit and the only struggle was the bulb retaining clip as the stealth bulbs are considerably larger, but it removed my headlights and just teased the spring over the bulb with pliers, the wiring was simple.and connected easily, worked first time and makes a huge difference to driving in the dark. Will be buying more of these for other cars now I've seen one in action and would happily recommend them to people. These were fitted to a Saab 9-3 2001

I could not be happier with the performance of the lights once fitted just a shame that some of the connections were missing from the box and did not find out until the garage rang to say they counld not finish the job !!!!

Took a risk paying £84 to a company at first time use without seeing their products in person... 110% that risk paid off successfully! 1 hour installation on my VW Bora (55) & now all I can say is they are much much brighter than I expected! I got the 6000k and expected them to be slightly more blue than what they are.. but that doesn't even bother me after seeing the quality of this product! Thank you HIDS4U!

The product is to replace a similar one purchased some years ago but has failed 10 years later, otherwise a vastly improved light from OEM and would certainly recommend.
My only complaint was the light I ordered for my car was the wrong item supplied, it was replaced promptly but although I ordered a 55W item, you supplied a 35W bulb.

Product was packaged well. Installation was made difficult due to lack of space in the headlamp cases which resulted in additional work to waterproof the main plug and sockets. Bulbs appear to give different beam patterns - one is quite precise and the other appears quite 'wooly' which results in a carpet of light with varying light intensity....bright and even from the good bulb and patchy light from the not so good bulb. Overall, it is a slight improvement over standard but not the 'wow' I had expected.
