My take on this having just gone from H7s to THQ lights with LED dipped beams is, the new set up offers a slight performance over the H7's, but not enough to justify the £600 they cost me. I can offset the value of my H7s against that if I were to sell them, but I don't want to before anyone else asks.
I bought them for vanity reasons, not the slight performance increase. Eitherway, both will offer noticeable improvements over H4s, providing you have all 4 lamps on with main beam.
The projector dipped unit in the THQ lights allows you to fit HID or LED and get a proper cut off so if you're wanting more output than a standard filament bulb those are your best options (though not legal) From all the photos posted on this thread there was one from amv with 35W HIDs fitted which in my opinion gave by far the best coverage.That's a great explanation @Mooncat thanks for that.
So, what would you consider as the best option for replacing the candle power of the H4's?
A good LED 'lamp' set, an original H7 unit or one of these LED units from THQ/travellinlite?

I have Transporter HQ headlights with sequential indicators.
Nobody else did one as nice with sequential indicators. I paid extra for the brighter bulbs, and I was bitterly disappointed with the dim lights output.
Everyone was flashing me, as they thought I was driving with just the DRL’s on as the light out out is so dim through that lens.
It came with instructions of how to code the ECU so
that main beam came on with the headlights.
However I ordered replacement LED bulbs for both the headlight and main beam bulbs from Autobulbs direct. Along with cornering front fog light bulbs. Used their own make that are supposed to be Canbus compatible. This was true for fog lights. But not for headlight and main beam.
I can only say go LED it’s literally pardon the pun......a night and day experience. Headlight and main beam’s were £50 / pair. And front fog lamps £40.
But for the investment both aesthetically and for functionality it’s been very worthwhile. Vs the standard poor bulbs.

Hi Andy, which LED bulbs did you get for you transporter in the end, could you tell me the manufacturer/model. Have you had any issues with alarms on the display or effects on the DAB radio?
That’s because u need to fit something like Philips led , any normal bulb won’t cut itHey Guys
I've just had Transporter HQ lights fitted to my transporter and the dipped beam is nothing like this above...
I purchased the better bulbs with the light units too....
H720 compact units will fit strait into my headlight units will they???
Thanks.![]()
