Hi all, I have an early model T6 (65 plate non ad blue). I've bought two different pairs of replacement drl bulbs with bayonet type fittings but no luck in getting any to illuminate. Original bulbs are "osram 7506 SL" I'm not sure if this is a wattage issue?? but the bulbs I've bought both...

That's really helpful, thanks for that. In terms of part number, is it a match do you think?

Since fitting LED H4 bulbs I am happy with the OEM T6 headlamps - I don't drive much in the dark and they now give off a nice crisp white light that is definitely brighter than stock bulbs. So, I wondered if anyone had managed to black out/delete the chrome bits either side that are an...

The codes for the bulbs can be found in the picture above ;) P21W PY21W W5W H4

...to be completed. :thumbsup: Only done 3100 miles since last year :whistle: Been ‘buzzing’ about in this since 8am :cool: I’ve nicknamed it ‘the ginger t**t’ Looking forward to getting my van back and refitting the small plates, LED H4 bulbs, air freshener on the rear view mirror etc etc.

Have a look at this thread https://www.t6forum.com/threads/h4-headlamp-bulb-upgrade.4741/

Hi All. Has anyone here fitted the Philips Ultinon LED H4 Pro6000's? Im in Germany and they are approved for the 7HC van. Philips claims they are canbus fault free, but...... 1. switching the high-beam both flash (pull) and constant (push) methods immediately gives Bulb error light. 2...

Here I am again, not 1 year later. Both Twenty20 are dying. Getting bulb error and de right bulb is flickering on its last breath. Not looking forward to swap them.... Any other experiences here? Alternative bulbs? Can I just have bad luck?

You can put H7 headlamp units in, fairly cheap, and these will let you put in H7 bulbs. Better than H4 which are so bad you literally can’t give them away. There are different brands of H7s which claim to be up to 200% brighter than your average bear. Better still is to fit LED headlamp units...

I’ve tried loads of different bulbs on the H4 at a fair cost and made not much difference then bought a pair of H7 off a fellow member for not much more than I spent on bulbs for the H4 and the difference is night and day! Don’t waste your money trying to make the H4 better there just bad units...

You are not comparing apples with apples. All you are doing is proving an H4 headlight is brighter with a more powerful bulb. No $h!t, of course it is! So would any headlight. And admitting to the fact the H4 has dark spots in front of the vehicle on main beam - that must be great. For those...

It’s just the drivers side I have. I ordered fog lights and that arrived. So I’m not entirely sure what unit it is. And it’s no use to me. I’m replacing my H4’s with THQ V3’s so will have the H4’s and also the original T6 rear lights spare if anyone is looking for any.

Pair of T6 standard H4 headlights removed from low mileage van, includes bulbs, no damage. £20 - Collection only (Telford)

I have a screw in one of the tyres - which would be a fail/advisory Wasn’t sure whether my rear pads were low so made sense to check Rear springs flap about when jacked up and suspension sagging - assume that’s a fail LED bulbs in an H4 headlight are not strictly road legal - although chances...

Lots of detail in the following thread - H4 to H7 Upgrade H7s are a lot better than H4 on dipped and main beam for the reasons mentioned by Dubber36. In my opinion they are perfectly acceptable and that’s in comparison to the all singing and dancing twin LED on my Passat. They are also much...

Generally speaking, T6 headlights are referred to by their (dipped) bulb type, so you’ll hear talk of the standard three options as “H4”, “H7” and “LED headlights”. T6.1 headlights come in either H7+H15 or LED options, so people often just refer to the halogen H7+H15 as “T6.1 headlights” and...

Hi Jaybee, It's all about preference. And if you have got a few weeks you should look through the H4 To H7 Upgrade thread, it has loads of info in it. I recently done the H4 to H7 change and have fitted the following bulbs. H7 Philips RacingVision GT200 12V 55W Halogen Bulbs (Pair) H7 lights...
