LED Headlight

I got the new LED bulb today in the mail. The swap over into a stock headlight fixture took a few minutes. The back of the LED is the same configuration as the stock bulb, so it drops in the reflector, you reassemble the fixture, and close up the headlight shell. No heat sink, no fan, no changing the fixture configuration to H4 compatible. I just dropped it in and closed it back up. It looks way brighter than the original bulb, but that's probably why many of you went to halogen prior to LED developement because anything is brighter than the original

It has an LED on the top side that's lit for the dip position and it uses both top and bottom LED's for the "brights" It seems like it's pretty bright. I'll have to go for a ride tonight and see how bright it is...

Wow, awesomely bright light, and with the high beam it's just fantastic. The odd thing is that when I rev the bike and let the rpm's fall back to idle, I get no dimming or brightening of the headlight what so ever. I've never had that before. Past headlights always dimmed as the bike rpm's fell to idle. The website says the LED takes 1/4 of an amp on low beam, and 1/2 of an amp on high beam... That's incredible for all the light it throws. I have to post the link because I think it's a worthwhile purchase since there is no modifying, and it actually gives more light while consuming less amperage....

You running a relay in your light system? Although, with the draw on this I think a relay would be moot?

I have been using one of these for 2 years,very bright, no mods needed. It works with negative or positive ground, plug and play.

I just bought this one. It plugs in directly, fits in the headlight shell of my MKIII (positive ground), and so far works great.

Does it have a center dip, or is it specific for left-side driving? Running light?

gortnipper · Oct 18, 2016

OK - looked up the spects, that one is for Right side of the road driving - 27291C is for left of the road driving.

EDIT: And these are $761.67 NZ here... like ~550 USD. Pass.

my GE Nighthawke cost about $254.00 NZ . Similar if not same as Trucklite.

No relay, and like I said previously,... I used to see the brightness of my headlight rise and fall with the RPM's of the bike, Now, the headlight is twice as bright and doesn't dim when I idle down, nor does the ammeter in my headlight shell deflect towards "discharge" when I flick the headlight on.

...Because I never had a halogen bulb with an H4 compatible plug modification to my headlight wiring harness, I bought a positive ground "drop in" LED bulb that fits the stock headlight fixture and has no heatsink or fan attached to it, So far it seems fine, and throws a much brighter beam with less current draw. I hope that answered your question.

Not sure what a center dip is. It has high and low beams, no running/pilot lights. Direct replacement for the H4 bulb I had in before. Pattern appears optimized for right side driving, i.e. more light on the right shoulder of the road.

Also, it only cost US$19.95 including shipping, so I thought it was worth the experiment.

Center dip means that the low beam neither biases to the left or the right. My lens on my 74 mk2 has a uniform lens pattern like this, so it is universal.

lcrken · Oct 18, 2016

Thanks. I hadn't heard that term before. The lens and reflector in my shell are an H4 motorcycle-specific unit. The lens is asymmetric, and is probably the reason it seems to illuminate the shoulder more. It has a small arrow cast into it that points toward the right side. The LED bulb itself appears to be symmetric.

When you go to this EBay link and put in 75 mark III in the "compatability" box it says"not compatable with this vehicle." Does yours work high beam and low beam with positive ground? I see it comes with two leads and thought maybe one was for positive ground. I'm running a similar LED not positive ground compatable. I have the leads reversed so without re-wiring the switch, I have only low beam. I would like to try this one if in fact the high/low plug posts will work with the negative polarity switch current. Thanks.

Actually, the picture on eBay showing two leads and boxes is incorrect. It comes with one box and one lead that fits a standard 3-prong headlight connector. It does indeed work with both high beam and low beam on my positive ground MKIII.

See on the photo 'Toyko Oki Smart can change from "+" to "-"

I have one too and it works in both DC volt flavours

I guess if these lights have something like a bridge rectifier in them, then they will work both ways.

$761 will near get you a pair of TRUCK LITES from COUGH COUGH & HAMMER , TWL, NZ road legal, unlike the led bulbs, I believe NARVA outlets want twice what twl are asking.
I run them in my landrovers and my bike and will never go back

Tried mine out tonight. I don't normally ride after dark if I can avoid it-too many critters and hard-to-see obstacles. This thing is bright! Little difference between the high and low beam, brightness-wise, just the aim. I'm sure an optimized reflector would make it even better, but at least I know if I get caught out, I can see my way home. Best 20 bucks I ever spent on this old crock.
