Truck lite LED's no low beam

[tage]

I bought a pair off EvilBay where the low beam does not work. It doesn't bother me as I see more on the dirt roads, however, am curious if anyone has any ideas as what burnt up inside them? I would blindly assume the low beam LED's burned out.

So all 10 leds light the whole time?

The light has 3 wires or 2?

Headlights have 3 wires...........#16 17 18.
Some that are not headlights but look the same have only 2 wires.

The wires are plugged in correctly, and have tested the output of the three plugs. It's definitely in the headlight unit. All the leds light up, but only with hi beam. They are the three wire units. 16/17/18 are clearly marked so I can confirm they're plugged in correctly...

Ive had 40 pairs in the past, and some only Hi beam worked.
Just have to replace it

What is wire 16? All mine were wired with 17 high, 18 low, and 91 ground.

 

[Recovry4x4]

91 is the ground and often it is mistakenly reported as 16.

16 to 91, is that like dyslexia only different

Anyone take these apart to see what the problem is?

Did you check the foot switch ?
I think you said you did. Not much else it could be except the lamp itself.
Just for fun switch the 17 and 18 wire.

Good luck, they are potted so you will have to mechanically separate the components.

Of course

it's 100% the lamp unit. I don't use the vehicle for on road use, and need the extra light on all the dirt roads, fields and what not. So I will never tear them apart to fix low beam issues. Not worth my time.

I might be off here, but a lot of "truck" leds sold on ebay specifically for Humvees are military specific non headlight models with no high/low, just on. Often times they are designated as truck led lights. Is this the case?

 

[tage]

maybe you're confusing truck led's with the actual brand name Truck Lite...
Anyways they should be universal application (7inch round), and not only limited to trucks. especially considering they come in 12v vs 24v units. I've seen both listed for sale, and more marketed towards the newer wrangler jeep crowds. Also have to take into account of DOT certified. They must have high/low.

ikoinu is talking about the 7" trucklite lamps that are sold as headlights on epay, but they only have on and off. no high / low / off.

Are you talking about the flood lights?
There's no way that it can be on/off headlights. It's not legal...

They look like headlights. They fit like headlights. But they only have high beam and off.

And no, they aren't legal for on road use as headlights.

yes, the floodlights. They have been listed on the auction site as "headlights" . I think ikoinu was just telling the OP to check and see if they really are headlights and not the flood lights. That could be a cause for no low beam.

 

[tage]

It looks like flood lights have a different pattern then the headlights, also they only have 2 wires (as 98 Golf stated high beam only). I have the genuine headlights; three wire. It's just the low beam doesn't work. Might consider those flood lights as auxiliary lighting if they go down in price...

There is some Clown on youtube, who promotes the idea of using flood lights as headlights , SMH.
Yes, they are illegal on the streets.
