Judging from these responses, is it safe to assume that most LED H7 retrofit bulbs are dodgy no matter the price?
All of these crappy websites selling this sort of thing are full of total ******** information. For example on the powerbulbs website they list the wattage as 1-2W...yeah, per individual LED maybe, but for the replacement lamp itself it's going to be ~15-17W.How about this https://www.powerbulbs.com/product/philips-x-treme-ultinon-led-headlamp-h7
Also appears from Philips AU website https://www.philips.com.au/c-p/12985BWX2/x-treme-ultinon-led-car-headlight-bulb
EDIT: Nevermind. Just saw the warning not suitable for public roads. But it seems Philips actually make headlights LED for H7 socket but not for public roads.
Are aftermarket hid legal? Seems a grey area. Another plus for led, is the fact is a bumper off and head lamp unit out to change bulbs so fit and forget would be great.
no grey area at all https://www.gov.uk/government/publications/aftermarket-hid-headlampsAre aftermarket hid legal? Seems a grey area
yes, you will pass MOT as they're not checked (assuming spread pattern is ok), but they're still illegal - which you should obviously know about when driving with such a mod.In the Department for Transport's (DfT) view it is not legalto sell or use after market HID lighting kits, for converting conventional Halogen headlamps to HID Xenon. If a customer wants to convert his vehicle to Xenon HID he must purchase completely new Xenon HID headlamps
actually, as of 2012 MOT changes, it looks like they could/should fail MOT, as the light's washers and self-leveling mechanism are meant to be checked http://www.ukmot.com/manual/1.7/Headlamps. Even if you have washers on the lights and a self-leveling mechanism then they're still not e-markedSo, all depends how thorough the MOT tester is...
UKMOT.com said:Vehicles equipped with High Intensity Discharge HID or LED dipped beam headlamps may be fitted with headlamp washers and a suspension or headlamp self levelling system.
Where such systems are fitted, they must work
Reason thats there is that some early HID cars didnt have washers.
Not sure to be honest. So far Ive seen differences in the following:
LED chip: Cree, Bridgelux, Lumileds
Cooling: Passive and active with Fan ranging from 5000 - 12000 rpm
PnP: Some do not require resistors for dash light warning
Lifespan: 20k to 50k hours
Looks: Some looks like a normal halogen without the filament/glass while others are like LED flashlights.
I find very confusing to be honest. So many choices.
Mine has a lot of LEDs as standard i just hope any units are easy to get into should any LEDs pop, can replace them with something a bit brighter then.Just as a comparison - my LED (stock) are passive, and are 'lifetime' for the car (i.e. at least 3 years).
