I would second HIDs and got mine from the same company, though I went for the 35 Watt ones. They are in a different league to the originals. You should not need a friendly MOT tester, I have had mine MOT'ed at three different places and not had a problem. If the beam pattern is correct they will pas the car as there is not actually a clear mechanism for them to do otherwise.

 

I agree regarding the HID's as I used them for years before swapping for LED's and couldn't see much difference but left the LED's in.

Not failed an MOT with either the HID's or LED's as IMHO the cutoff is better than with the original glow worms so safer for oncoming traffic and me as you can see so much better.

 

These are the same one I fitted, and I too went for the 55w ones. I've had them in coming up 3 years, and gone through 2 MOT's without issue, with a 3rd MOT coming up soon (or not as the case may be). The difference between these and the standard bulbs is considerable.

 

Having read as many posts as possible regarding the various routes people have taken to try and improve the pathetic lights I'm now pleased to say that after a few false starts I'm finally satisfied with the results. My car is a 2013 Chevy Volt.

My first change was to try a good quality normal bulb upgrade...... (not much better) then I purchased some Novsight LED's. They were well packaged, good quality items and really simple to fit, working without issue. But while they were better than the standard candles they still didn't give me the brightness and range that I was looking for to make night driving, which I do a lot, the safe experience I was looking for.

After pondering over fitment, potential heat build-up and possible MOT issues I decided to order the 55w Stealth X HID Kit from HIDS4U.co.uk.
Part Number: HIR2ULT55W6HB

HIR2 HIDS4U Stealth-X 55W Xenon HID Conversion Kit

HID conversion kit for your vehicle. This system uses just 55W ballasts to produce an immense 450% brighter light when compared to standard bulbs. HIR2 HID kits are the ultimate headlight upgrade within the automotive industry.

Although they were out of stock initially they soon sent them and it only took a Sunday afternoon to fit them. The only modification needed was to drill the centre of the weather cap on the back of the light to accept the grommet/cables and then find a space to securely fix the ballasts, nothing beyond the competent home mechanic. The kit is very good quality and fitted without any modifications.

I'm delighted to say that after about a month of use including around 1,800 miles of night driving they are working perfectly, no faults or warnings on the dash, no issues with heat buildup that I can detect and the improvement in lighting is quite simply immense, with a sharp cut off and not a single person has flashed me to complain of their setting.

I appreciate that I may have to rely on a friendly MOT tester but I have the original bulbs in the car so could if required swap them back out in minutes.

If you are considering this as an upgrade I would recommend it from my experience, I no longer even think about lighting issues and have now turned my attention to the other fixes that need doing, next up unlocking buttons on the door handles!

Stay safe

PS: If anyone is interested in the LED's drop me a line....
