Led taillight upgrade issues.

[turbinesurgun]

I've searched and asked fb forums with no luck. Put on the grote led taillight covers today on my 998 and won the 3 lever switch in stop/turn I'm getting enough voltage to light the led's up when I should have no light at all. Do I need to have some resistors added? I'm ready to give up on the led tails. I have led headlights, new turn signal switch, new flasher and new 3 lever switch with bulb in and bulb removed. Any help greatly appreciated

did you put in the newer style electronic flasher? as long as the front lights are still normal, there shouldn't be an issue.

FLASHER, THERMAL......11613631......5945-00-789-3706

Put an LED bulb in the turn signal switch. That worked for me.

The flasher is brand new but I don't know if it's new style. I've about come to the conclusion that I'm just gonna put a set of new metal housing lights on the hmmwv and the led's on a trailer. I'm aggravated

 

[turbinesurgun]

I will try that. Where did you get the led if you don't mind my asking

Do you have metal or plastic tail light buckets in your vehicle? The metal housings inherently ground both mounting bolts but you need to strap the two bolts together if you have plastic housings since both bolts need to be grounded. The HMMWV is notoriously bad when it comes to ground issues and you need to make sure everything electrical makes good grounds either through the harness or through clean contact with the body. Remember star washers are definitely your friend when it comes to HMMWV electricals.

They are plastic and grounded well. Can you explain how they would light up if not grounded well? Seems like if they weren't grounded well they wouldn't light up.

LED light test :
Tested the directional lights and found :
With all four Grote led's , and a incandescent light bulb in blinker switch : thermal switch made by Swiss controls [ 12418344 ],
Aurora Cord [ 11613631 ], and Riverside Mfg. [ 11613631 ] lights work as they should.
The Nartron 11613631 won't work, unless you change the 1819 incandescent bulb in the blinker switch with a 28 vdc LED bulb.
First pic is a Nartron
Sec pic is others listed above.

That was my issue then. I have the nartron. I swapped the lights out today but if that will cure them I may put them back in. Thank you very much

I tested 25 Nartron units...they all did not work until I changed the bulb in the switch to an LED.

 

[turbinesurgun]

Can you tell me the number LED bulb you used?

Its not bright, but it worked for the test,,,12360890-3.
Type base is bayonet, Ba9s [ 9mm ], 28vdc.
Standard bulb is a 1819

Can someone post a pic of where the new bulb goes?

Put it in the turn signal lever on the left side of the steering column.

Great info on this site. I have a 1995 M998A1 that came will all LED lighting (tails, side marker, front markers), but no headlights. I tossed in some functioning non-LED headlights and all the lighting works except for the brake lights and rear turn signals. I tested the brake switch and it is functioning correctly. Turn signal seems for function correctly and properly triggers the front signals. To complicate things, the passenger tail light did not light at all when I first picked up the HMMWV, but now it does. However, the driver's tail light is brighter as if it is stuck in the brake/flasher mode. I have checked all connection points for corrosion/proper contact. This mv has the Riverside Mfg. [ 11613631 ] thermal switch.

Thoughts?

Thanks.

Has anybody tested the LED functionality when using the civilian/aftermarket Novita/Tridon EG22 flasher module?

Thanks,
