Are these halogen or LED bulbs in these THQ mkII units?
I don’t have them but I’m pretty sure the dip beam and main beam bulbs are halogen.
I have only replaced my H4 halogen bulbs for those H4 LED bulbs I linked to above.
I’m an idiot. I meant to reply to @Smr72 ..!

Look smart. Do you have any bulb error lights on the dash?
At Smr72 and are the LED H1 and H7 lamps those supplied with the THQ Mk2s as I think it was on their sister site CamperGlass where it read like the new Mk2s were MOT compliant with LED lamps fitted... I could be making that bit up or more likely wrongly attributing the claims out of blind optimism.
Cheers Zombie, will add the links to my list, was originally looking at some Twenty20 lamps on ABDs site after buying my LED DRL lamps and getting no errors and a satisfactory eye watering crisp white light, weirdly the cheapie LED wedge side light lamps don't throw up a fault either and they were a fivers impulse buy so happy there too.

Zombie do the lamps in your link fit in the housing as according to the advert they're 90mm deep, just wondering if the caps will clip back on with these bad boys onboard?
@Stay Frosty i got mine on eBay
Cheers chap!
Anyone have any experience with these?
H4 Twenty20 Compact LED Headlight Bulb
The advice from the manufacturers is that although not technically legal they will go through an MoT fine but I’m interested to know people’s experiences in terms of brightness, lifespan etc.

Loz will be best placed to answer but I spoke with a mate who does MOT's and he said definate fail. No way would they pass.
I considered these too but was unsure of the legalities around insurance or an accident using led headlights.Instead I went for the H4 halogen 150%, led DRL's and led sidelights (all Twenty20), purchased from autobulbsdirect which I think must be an affiliate of HIDS4U.
Very happy with second hand H7 headlight units in place of the H4.
Proper H7 driving lamps on main beam, much better than the H4 units.
Considered all of the LED and high power alternatives but reliability and MOT made the H7 look like good sense.
@Ed Webb posted a very good thread on the conversion

I've been really happy with these What Have You Done To Your Van Today?
They were only supposed to be a temporary solution but they're so good I've just dropped the idea of upgrading my lights altogether. I'll probably have to take them out for my MOT in Feb, but I might leave them in anyway and if they fail just resubmit it with halogens in for the day. If I do upgrade it will be to the full factory LEDs, I can't see the the factory H7s or the chinese copies being noticeably better at light output so I'd resent spending £3-400 for no real benefit.
This might be of interest, but bear in mind these are for projector lights. Not reflectors like your H4s. They will just scatter light all over the place and dazzle other drivers. Some say they don't get flashed, but that doesn't mean that other road users don't find them offensive.
