What bulbs did you fit in yours? I am looking to either upgrade to THQ V3s or wait until the full LEDs come out. Cheers.

Yep, on H4 the filaments swap over when you go to high beam, rather than both coming on together. Coding both together with H4 is probably not a good idea due to excess heat as mentioned. Especially in a plastic headlamp!

Really sorry to sound pessimistic it’s really not worth spending the money on bulbs for the h4’s I done it and learnt the hard way! Save your money until your ready for an upgrade

I went for the H7's because I just wanted a better dipped beam. I know H4 have same 55w but my H4 with 200% Osram bulbs are still terrible, will the H7 beam be much better?

I recently purchased full LED headlight units to replace the factory headlights, which originally had H4 bulbs. These new headlights are advertised as plug-and-play, but the seller mentioned that programming might be necessary for the high beam if the factory units used H4 bulbs. To avoid any...

Yep. Look on the sticker, it says H7 H7 Whereas the H4 says H4 some other bulbs

His expression looks like he’s been asked if there are better bulbs for H4 head lights.

Morning, I've recently had the headlights upgraded on my T6 to v3s, so have a pair of working H4's if anyone fancies them. Off a 67 plate in decent condition with bulbs. Collection from Chichester.

I bought this set of H4 bulbs and there is a significant improvement, I will not change to H7 for now OSRAM NIGHT BREAKER 200, H4, +200% more brightness, halogen headlight lamp, 64193NB200-HCB, 12V, Duo Box (2 lamps) [Energy Class A]...

They come with standard bulbs but missing the side light bulbs. One mark on the offside headlight, see photos. £25 for the pair, collection only from Gloucester.

Yes.

...beam. The surface area of the H7 reflector is much larger than the effective dipped beam producing part of the H4 one. Also factor in that a H4 bulb has a shield over the filament to direct the light to certain parts of the reflector. A H7 bulb doesn't have this and emits light through 360°...

For Sale Pair of H4 Headlamps complete with bulbs Taken from my 69 plate Kombi. £40.00 collected from Stalybridge/Greater Manchester Cheers for looking

Make sure to enable both bulbs on when on main beam.

I'm presuming that you have H4 headlights? If so, HIDs won't work. The halogen bulb has two filaments. One for dipped and one for main beam. Each one focused on a different part of the reflector. HIDs are a single light source that will give you essentially main beam regardless of which beam...

Or get some THQ H7 reflector units and consider their H7 led bulbs for the ultimate H4 upgrade solution

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...

...if it's been mentioned about why they need coding, but with H4's when you switch to main beam, dipped beam goes out. As you probably know, H4 bulbs have separate filaments for dipped and main beam. If both are lit together, the bulb will get too hot and go pop. The H7 lights have a bulb in...

Hi, I’ve seen the led bulb upgrades listed for oem t6 headlights. Stating canbus error free! Anyone upgraded their bulbs to led and which ones did you get? I’ve done the front fog upgrade and rear lights. Want the led for stock headlights mow Tia

Hi all, Having a bit of a mare with left hand DRL. Light bulb out light came on, narrowed down to left DRL in a headlight unit that has been replaced from H4 candles to H7, with no problems. Replaced the bulb, warning went off, presumed solved but same again, presumed dodgy bulb, so bough...
