The actual bulb connectors are an integral part of the headlight unit. The headlight units themselves both have the same wiring configuration and plug on both H4 and H7 variants
H7's are plug and play. They have seperate DRL's just like H4. Only thing you might want to do after fitting is change the coding so the dipped beam stays on when you turn on high beam.
Have a look at @Loz post here

If the T6s are H4, you are best off chucking them in the skip. Nobody wants them for free from what I have seen. You can keep the rear rubber and plastic bulb covers as they seem to fit H7s and people do buy them on ebay. I actually enjoyed taking mine to the dump; felt like an end to a very...
Hi. Don’t know if you could give me any advice too, I have the same problem, the DRL On the near side has gone out with the warning light now on the dashboard, behind the light is the battery. I took this out but the bulb seems to sit below which I couldn’t get access to. The van was in vw...
I have the GT200 as well and am very impressed, even with mine being H4bulbs.
I’ve always had the ‘upgrade’ offerings from either Philips or Osram and find Philips to have the edge in terms of beam quality and lifespan so just go for their best claimed bulb at the time.
Interestingly when one...
The most cost effective T6 headlight upgrade from the crappy H4's.
Here's a pair of H7 Headlights with almost new Osram 200% Nightbreakers and Twenty20 LED DRL upgrades. New bulbs were installed March 2023. Headlights were removed from my van in October 2023, so bulbs less than 6 months Summer...
Hi I have a new panel van t6.1 and I must say the lights as horrible with every else at the moment not sure I can go for headlight swop just yet
Can you change the bulbs at least to improve view and light at the front with no problem or errors cheers
Hi all.
Does anyone have the THQ headlamps with the racing vision H7 bulbs.
I am going to upgrade from the pathetic H4's
I have searched fleabay but can't find any genuine H7's.
I can get some Depo ones cheap but I don't think they will be good quality.
I can get some genuine ones from...
Hi. I have a singular passenger headlight for sale, removed from a 2016 (35,000 miles) to upgrade to Transporter HQ’s (driver already passed on to a friend of mine).
Ideal if someone has a chip/crack or has bumped theirs (will even leave the bulbs in ;)) (£50) (Just outside Chester)
Thanks for that. I did have a set of LED DRLs in my H4 headlamp which didn't trigger the bulb warning light, so might try swapping and see what happens.
Thanks for the help.
Thankfully I just need to swap my metro plates! Even then not sure they'd fail it! Got till Sept to wait unless get a cancellation. Was up on 11 April I think! Good old NI!
I went from H7 to THQ for vanity reasons.
The H7s are as good as any other modern twin beam reflector headlight. They are perfectly acceptable and it wasn't until I drove a van with H4s that I realised there is a vast difference between them. So absolutely a worthwhile upgrade.
The THQs are...
I look for the hole in the reflector with the little bulb sticking out.
Hole outside of the bigger bulb =H4
Hole to the inside of the headlight =H7
And as @dubber36 says, H7 with the DRL under the main reflector, H4s just a black void!!
...some H7s bought off Facebook Marketplace for £70 plus some better bulbs and LED DRLs - all in £110. I'd say don't waste your money on new H4bulbs as they will make very little difference and you will still be looking to upgrade. Invest the saving on some H7s or if you are feeling flush and...
Did a bit more reading about the THQ lights (on this forum) and there seem there have been a fair few sets for sale 'lightly used' and a number of people who aren't that pleased with them. I will focus my efforts on picking up a set of the twin H7 units instead, I think.
I don't really want to...
I upgraded my bulbs in my H4 units to the Osram Nightbreakers. Much better than standard and fraction of price of changing the light units. I know they are not nearly as good as H7 etc but I am happy with the difference compared to how much I spent.
