Led headlights have arrived

and by cold it dropped from 60 deg to 19 deg that night its 3 deg this morning
 
It was about 8 degrees here Friday morning,with winds gusting to 60 mph for awhile...yesterday ,3" of snow fell in as many hours,which messed traffic up royally,many accidents--today it is 48 degrees at the moment,all the snow was gone at 7 am when I awoke,(Yaaay! :d)--and rain is expected,possibly heavy & some thunder and gusty winds,and the temps may hit 60 degrees..--Tomorrow morning is supposed to be 15 degrees with a high of 26...:screwy:...
 
The military has gone iver to all LED headlights. The ice/snow thing hasn't been an issue.
 
Sorry, just what the truck lite rep told me that they were doing a couple of years ago.

And I have had my plain old halogen headlights almost covered from snow and ice. On my Chevy, and several Kenworth trucks. More so with the 7" round than 4x6. So I would be cautious with LEDs in wet snow. I believe that the headlight and bezel area can make a difference.
 
Hey guys, I too swapped these LED lights in, but am having 1 problem.

Low beams work great; High beams however do not work. Already have a new headlight switch and dimmer switch. When activating the dimmer switch, I hear the click and the bright indicator on the dash lights up, but no light from the head lamps. This is weird to me, because the whole reason I swapped the headlight and dimmer switch was because with the old sealed beams I only had brights, no low beams. Driving me nuts. Any help would be appreciated. Wondering if resistors needed to be added to make the high beams functional. Thanks.
 
Thats what I was kind of thinking too, but wouldn't at least my top ones (low beams with 3 prong connector) switch to high beams at least. (Mine has all 4 that come on with brights... at least before they did hahaha :-( I will double check the lower ones and report back. Thanks Kain
 
No luck, changed the wires around. Cleaned the grounds attached to the frame... I know there is power to the tan wires at the plug, I know the LEDs are good, tested a fused line with the battery, all light up. Started snowing, so will have to try later.

This is the exact problem I'm having. I even used the LMC harness since I'm a wiring dummy. I have power coming from both hi and low beam wires but can't get it to work. If I wire the high beams the low beams don't work and vice versa.

Exactly Desert...I'm going to keep researching, will let you know bud
 
Well... Kain was right, I assumed the negative wire would be the same post on the high beam as the low beam... Wrong. I swapped the negative (black) wire on mine to the opposite side and whala... It worked. I now have brights and low beams. Thanks again Kain
 
And mine is an 88

ya for some reason you have to switch the wires before it works properly.
what i did is just turn the lights on without the engine running and switched em till it worked.
they dont draw enough amps or power to hurt it

Are you switching the wires at the 3 prong connectors?
