If you buy these LED headlight bulbs from Ebay ..

Then when fitted they're prone to breaking like this when the connector is pushed on ...

And if that happens when you're fitting the bulb, it leaves the problem of extracting the remains from the headlight shell ...

Wait aren't LED front headlamp bulbs sketchy on legality anyway?

In that new cars and stuff pass EU/UK regs and thus are allowed but you can't really retrofit them to older vehicles if not type approved.

Anyway looks like a nose fairing off and a bent paper clip job to get it out.

Forewarned is forearmed. Anyone buying these needs to apply some extra glue of some sort or even a bit of silver soldering?

Poorly spot welding,
The quick fix is to carefully supplement the spot welds with some solder as suggested

Looks like a crap design as how is the heat meant to leave the headlight enclosure?

All the semi decent ones I've seen have the heatsink and fan out the rear, so heat is being taken away. With minimal air flow in/out of the housing, that fan is just gonna stir the hot air around a bit.

How they usually look.

Those things just look like a fire hazard to me or melted wiring harness, i had a dodgy led bulb melt an interior light on my car, never again.

Poverty-spec LED bulbs have poverty-spec build quality.

Who knew?

The lens and reflectors are of different design so that the light is projected properly and the colour is correct.

The lamp may be in a different position too as wavelength will affect focus which if not corrected will produce glare.

That was my first thought, but remember a standard bulb is 60W, so dissipating 20W from the LED shouldn't really be an issue.

Be careful, I tried a few years ago now to try and upgrade the lighting on a couple of bikes, the light pattern given off by the led's was awful. I tried a couple of different makes, including ones where you could adjust the orientation of the 'filament', I never did find any I liked. So, I just went for a bit more powerful standard bulbs.

Still, technology has probably moved on, and there may well be improvements to teh design of the bulbs ..Also, bear in mind, not all led bulbs have hi & low beam functionality

LED's are not measured in Watts. They are measured in Lumens.

But if your average bike bulb is 55W

WTF would you fit a claimed 20W one?

Heat dissipation is still measured in Watts (Or Joules or BTU, but most commonly, it's Watts)

Light output is measured in Lumens. Chances of any of the cheap ones bulbs being put in an integrating sphere/globe for a real measurement however, are slim to none.

Have you not seen any LED bulbs? We have 5W LEDs in the house which replaced 50W GU10 halogens, so a 20W LED should be putting out significantly more light than a 60W H4. Whether that light ends up aimed correctly is a different matter of course.

By the way when I was looking at stuff to do with headlights, I found out that standard bulb wattage is for 12.0V, so in reality when motoring and the voltage should be nearer 14.0V, a standard H4 will be drawing (and dissipating) more like 75W. Headlight Bulb Test Results

Wavelength? Seriously?

We're not talking precision telescope or microscope optics here, just a crude reflector and prismatic lens. Laughing

Seller's offered me a fiver refund. I've now fitted the one that's not broken, let's see how it does on the road. Tests in the yard suggest it shouldn't dazzle when dipped. If it works OK in practice I'll make a counter offer - either send me one replacement or refund £6.49 so I can order a replacement. Possibly I can fix the broken one with epoxy as a spare. If he won't play ball he can have them both back. Meantime I have one white and one yellowish headlight.
