I too am going to do this headlight upgrade and wonder if anyone canhelp answer a question I have ?. On vehicles with factory fitted H7 lights, does the main/low beam stay on when full beam is on ?. Way back in 2004 I fitted twin reflector lights in my T5 174 and modified the wiring so that...

The reason for the bigger lights is to hold more candles for us chaps with H4 bulbs :(

Thanks for the reassurance @PukkaT6 and @Colinlp I've already upgraded the delightful H4 bulbs to the Phillips 150% bulbs still not great but just about adequate, just need to change the side light to an LED version, the little yellow light now looks awful. Can't imagine how small your...

FYI, have just ordered Philips Extreme Vision H4 bulbs through Amazon Prime Deal Day offer for £12.28 post free, which seems like a good deal. Deal finishes tonight I think.

I was reading about the options for replacing the VW candle bulbs and i noticed that someone said that Phillips were releasing a H4 LED, well i had a b it of a look and they are out and wanted to know if anyone has fitted them. At $240 AUD they aren't cheap, but cheaper than a full led...

I really want to upgrade my headlight bulbs. Going to do this when she goes in for her check up.

Saying all that I used to use 100w H4 bulbs on my Mini back in the 1970's, and had no problem with them. Kept them for future use and fitted them on a later Mini only to find the current was too much for the switch which kept burning out. They are illegal on road cars but I doubt any one would...

@Phantom ,The standard H4 fitment is poor, this might be in part due to a long life h4 bulb being fitted as standard, the normal life being an option.... You can gain a light increase by fitting something like Osram night breakers or Philips extreme 130+ etc.. other than that you might be able...

Nope, its not just H7 bulbs. Even VW would not get away with £456 for two bulbs. It specifically says that it adds twin headlights, so basically instead of a single H4 on each side it has twin H7's. Everyone complains bitterly about the quality of the standard lights, whereas I am perfectly...

£456 To replace a pair of H4 bulbs with 4 H7 bulbs. Quite a gouge for two additional bulbs if you have already stumped up for Highline trim. I asked the dealer about the H7 option and he said not much difference from the standard headlights. The LEDs will be expensive to retrofit.

Hi all I have just ordered the Phillips H4 bulbs for mine but what are the other 2 bulbs I need???? Thanks

Anyone fitted any led H4 bulbs yes with pictures before and after and fitment ??

Loads of people on here have.. they're probably the most common bulb upgrade

Has anyone tried Phillips Racing Vision +150% H4 bulbs? Buy the Philips RacingVision car headlight bulb 12342RVS2 car headlight bulb

I'm also in a similar situation having done a deal with a standard H4 van that was offered with a huge discount, hopefully given time the LED conversion will come down in price (Currently £2250+VAT) or an alternative will be available? In the short term I'm going to get some brighter H4 bulbs...

Ok, I've decided to 'upgrade' the H4 headlight bulbs. New bulbs have been purchased. Any hints 'n' tips as to the best way of getting the 'old' bulbs out...? It's pretty straightforward to loosen the metal retaining clips and remove the black plastic caps over the rear of the headlight unit...

Test them first, before trying to fit them, I fitted mine and then had to take them out because of bulb failure light on the dash, just take the conection of the back of the H4 bulb on the near side as you have a bit more room, plug the philips/Led/ Hid units in one at a time, just leave...

I dont know how long you have had them, but honestly 5 min job to test, use the passengers side, take off the dust cover pull the lead off the back off the H4 bulb and plug it into the Philips unit, just let it sit on the bonnet slam panel, try hi/lo beam and see if you get a bulb failure light...

H4 bulbs has twin filament and H7 has one filament. Therefor i guess the light output in one H4 bulb is lower on dipped compared with H7 on dipped since the dual filamet on the H4. Also the H4 has three connecting pins on the back, and H7 has two. My father had the same issue on a Kawasaki...

Right then, installed the Philips 150+ racing vision H4 bulbs. Been out for a drive and honestly I think the improvement is significant. Previously, it was hard to tell on totally dark roads if the lights were on. If another car approached or if there were any street lighting you couldn't see...
