Search results for query: H4 bulb

Had these (T6) H7 headlights in the garage for a while and never got round to fitting them, I ordered some new bulbs for them the other month and they are still in the packs (led driving lights, whiter side lights and whiter/stronger dipped h7 - all recommendations off here). I've taken the...

Back in the old days when I was using both filaments on my H4 surprisingly I haven't experienced any bulb failure. Instead the bulb was generating excessive heat and eventually over long period of time causing heat damage to the shiny reflector surface. This was resulting in permanent damage...

last (dumb) question, I need to buy the caravelle headlights and cant simply switch the H4 for H7 in the existing headlights?

What are the chances of both bulbs failing at the same time? I’d be looking somewhere else first. Wiring/fuses etc. I’ve had those Twenty 20 fitted for quite a while no issues and I know a few other people on here use them also. No one has previously mentioned a failure as far as I’m aware.

Free to a good home a set of H4 headlights complete with bulbs, no damage in great condition. Collection only from York area.

Has anyone tried the Osram nightbreaker 200 H4 bulbs as replacements for H4 headlamps? They seem to quite new, out here in Oz at least.

There’s some recent comments on the H4 to H7 thread where a few of us have used the Twenty20 drl can bus led from Auto Bulbs Direct with no issues.

As above, H4 headlights taken from my 2017 Kombi at 29K miles. Pickup in south wales (just outside Cardiff) or can meet locally for pickup. 150% bulbs in main beam/dip and LED's in the DRL Will also consider posting if interested, at buyers cost as I have the box and wrapping from my new THQ...

Coded out my dipped/main beam LED H4 bulb warning with VCDS. Fitted these Kombi floor blank caps that were 3D printed (not by me).

I have the Philips GT200 as an upgrade H4 bulb and it’s good enough for me. I sold a Citroen Xantia back in the day just because the headlights were so bad - that’s how fussy I am. You can buy Philips LED upgrades now but despite them lobbying for years they still aren’t classed as road legal...

Pre-MOT preparation today. Fitted standard size number plates after drilling holes to suit Fitted H4 candle bulbs after removing the Novisight H4 LEDs Removed all four wheels and checked tyres, checked for nails, checked brake pads, shocks, brake hoses etc. Got the wife to operate the lights...

It’s a minefield. You need to figure out which headlights you have first, you can tell by where the bulbs are placed within the headlight. If H4 you can upgrade the bulbs to ‘whiter’ ones but don’t expect much extra light. If you want more light you’ll have to do some modifications or change the...

Sorry to open an old post, but have just changed the drl in my t6 2018 from h4 (will change back for mot) to led. Hated the orange look and replaced with twenty20 382 led bulbs. All good. However, thought I could do the same for the reversing light (torch more like) as can't see anything with...

Long time lurker here.. Got a 2018 van, fitted with the utterly shocking (dangerous, stupid, rubbish, pathetic, etc) H4 headlights and need to make a change. Also have a 2017 Passat GTE with LEDs, so a bit spoilt and know what good lights should look like, but can't justify the cost of LED...

I've read reams of posts on here many saying that they have successfully changed the standard halogen headlight H4s to LEDs but had to mess about with cutting holes in the rear light covers and adding resistors to stop flickering headlights. As LEDs are getting better all the time, are there...

I was passed by a T5 this evening heading north on the M5 and it had LED ‘bulbs’. Not sure if they were OE but there was a glare issue in my drivers door mirror. Looking at the pool of light the van had in front I’d say the lights were pretty well aligned but the output was no better than my...

H4 is the bulb type used in the standard headlights.

So all headlamps have vertical and horizontal adjusters on them, these being circular white-colour dials that you adjust with a 6mm hex or cross head driver. The reason I asked about yours was the remark: The OEM LED headlights have automatic level sensors on the front and rear ARB which...

...headlamps: https://www.t6forum.com/threads/h4-to-h7-upgrade.10008/ Failing that, there’s other threads in that electrical sun-forum detailing aftermarket or OEM LED installs. Let us know what you end up choosing (unless it’s just LED H4 bulbs… no one likes being blinded by those when...

Morning T6 Brain trust. I've got a 2015 T6 startline with the H4 bulbs. Just fitted better bulbs but was wondering if there was any vertical adjustment in the headlight as even on the hiest setting on the adjustment knob in the cab they are still too low. Can't find anything around the web so...
