Has anyone tried LED headlamp bulbs?

Recommended Posts

Just wondering if anyone has experience of H4 led bulbs, and are they any good?

I've got crystal clear headlamps, the really annoying Dim city light setting....really must look at chopping that out.. and was wondering if the LED bulbs are as good as they claim.. HID quality?

Which is probably the biggest single thing I miss about my L322,  just don't miss the screen of doom and bong of death... L322 thing BONG! your suspension is broken please fork out another £1000 to the Stealer to go on!

The chat brushes on the topic of the bulbs here... I've been looking at them for a few years now, but not really all that confident with the direction of the technology, as they are so hi power they need some pretty good cooling, and it looks like most are now being installed with small computer type cooling fans that evidently need a fair bit of attention and seize up pretty easily...

I could be wrong, but i seem to remember them being illegal as is the case with aftermarket HID bulbs in halogen reflectors.

I have a set of these and am quite impressed.

ebay link

Supposedly DOT approved. Mine are E marked (although link here is not from the same supplier i bought from, so check)

they will fit a defender, and better cooling as bowl is the heatsink

Edit: Yes it seems i was correct Link

And buying a whole lamp unit, which is E marked (genuine or not,  you make your call) seems to be ok

The biggest problem with those complete light units is the techrical (deliberate) destructions and specs are not in the best of Engrish and the question of RHD / LHD comes in to play... Bearing in mind that the majority are listed as Jeep Wrangler first, which is predominantly LHD in America (which is a massive modding market), I have grave doubts that you'll get RHD lamps from a Chinese supplier... And I also have my doubts about the 'E' marks....I'm sure my headlamps have an E mark and RHD on them... there is no RHD mark on any of those LED units.

Anything that is spec'd for the RHD market appears to suffer from the Range Rover pricing syndrome... add the words Range Rover to the description and the price goes up x3

Example a full set of aero wipers for my Mercedes ML £6 just the 2 front for my old L322 £18 :angry:

American beam pattern is flat and has no kick up therefore not left or right hand. My crystal clears (halogen) are American pattern, E marked and according to my mot man perfectly legal.

I've just bought some LED bulbs and photographed a comparison with them, the std halogen and HID bulbs in the same unit,

I'll try to get the images up tonight, but I was very impressed with the LEDs and I specifically chose those without fans for cooling.

Well having done a bit of googling I found out that a headlamp can have LHT, RHD, or an Arrow pointing right facing the lamp... if there are no markings other than DOT or Exx then they are for LHD applications... I didn't know that US bulbs were flat, I thought that they kicked up to the right. And what the implications of fitting flat beams are I'll have to have another nosey...

And muddi camel I look forward to your reply, you might find this helpful! https://forums.lr4x4.com/topic/102189-how-do-i-add-photos/

So running on that logic, if they have a DOT and an E mark they should be OK, just steer clear of the E only marked ones!

No; DOT is US spec, E is EU spec, and both will be LHD, so having the two together means nothing in UK regulations.  You may find CE marked RHD lamps, which would be legal here, but of course the Chinese stick that label on anything completely fraudulently.  It'll be easier after Brexit, because you'll only need to worry about the British Standard kite mark.

^ if we ever get there....^

If a lamp is DOT marked it's US spec, so flat... if it also has an E mark then you can use it in the UK 'legally' (based on the legitimacy of the E mark)

BUT if a lamp just has an E mark and no DOT, it is EU spec only, and like us their lights kick to the side, only to be awkward theirs go the opposite to us... So no DOT, no use here! Unless it has an arrow pointing to the curb, RHD, LHT, or a double ended arrow which means it's flat beam.

I seem to remember reading somewhere that a lot of modern car now have flat beams as standard.

I guess it removes a cost of having left or right hand drive versions or having to include mechanics for switching.

Says Flat beams are OK for the MOT

Err, no. For lots of reasons, no. 

Firstly CE marking does not apply to automotive components, they are e-marked instead. Secondly, CE marking isn't going to go away with Brexit, no matter how much some may wish it, and thirdly, the Kitemark is not and never has been a national safety mark for the UK, it's a registered trade mark owned by the British Standards Institution who are only one of a number of bodies who can approve products of all kinds.

There used to be BS iso but I don't ever recall seeing that of car parts.... I do recall seeing a lot of parts with PAT PEND! and MOWOG... maybe they were the standard! :wacko:

As far as CE mark goes, you are correct it is just an E and a small number (1-14 I think) which indicates which country tested the lights.... that's probably another countability ploy from the HSE, I'm sorry the profanity scanner has missed that one!

So we are back to it needs the E mark to be legal in the EU and it needs the DOT mark to ensure it is flat beam and pasases the MOT, or it should have a double ended arrow pointing left and right.
