Really happy with the end results. Got all the running lights working like they should, except for the Hazards, which I never use anyway. Wasted a lot of time going down the internet rabbit hole of conflicting recommendations, but I got there eventually. 😁 If you guys are thinking about doing the same thing, it's mandatory you get a Blinker Genie 2 (For Side-Markers) and Electronic Flasher.

Looking good! :chug:
 
When I did this, also had an issue with the hazards. What I found is you need two electronic flashers - one for the blinkers and one for the hazards. The CJ fuse block has two flashers in it for these two uses, but of course uses mechanical flashers and LEDs need the electronic ones. What I found though is that the polarity in the fuse block is reversed in the two flasher sockets. For those not familiar, the electronic flashers must have the + and the - connected properly to function, whereas a mechanical flasher doesn't care. So if you buy two of the same type electronic flasher, they will work just fine, but you must reverse the polarity for the hazard socket in the fuse block. Two options here: (1) move the two wires in the fuse block to swap them, or (2) get a polarity reverser. When I purchased my electronic flashers, they came with the polarity reversers. I used one for he hazard flasher and didn't need the other for the blinker flasher.

Thanks for the feedback. I just to make sure I understand what you're saying. So even though the Turn Signal electronic flasher works fine, there's a good chance the polarity is flipped on the Hazard electronic flasher? I'll check it with a voltmeter today. Thanks!
 
That is correct. The blinker flasher socket is correct polarity for the electronic flasher unit I used, but the socket for the hazard flasher unit is reversed polarity. So while I used the same electronic flasher part # for each, I had to use the polarity reverser for the hazard one.

Thanks bud! Just ordered the reverse polarity adapter. I'm kicking myself for not ordering the combo item. I just assumed that if turn-signal flasher worked, then the hazards would be wired up the same way. Thanks AMC!! 😁
 
I just installed a couple of the United Pacific 90650 flashers in my 3B a few weeks back. Work well even though the front parking/turn bulbs are still incandescent. Anyone know a source for the dual element 1156 base LED bulbs? I tried filing off the high pin on some 1157 base LED's but they are too loose in the socket with only one pin holding them.
 
The 1156 is a single element bulb, whereas the 1157 is a dual element bulb. Are you referring to the bayonet pins as what you filed off an 1157? Amazon has lots of 1156 type bulbs in LED styles with the standard bayonet mounting.

Hey TSB8C! Put on the polarity reverser, and now the Hazards work great. Thanks for the help!

I love my LED conversions - tail lights, head lights, side markers, front blinkers, under dash courtesy lights, Dakota Digital gauges with LED lighting, the dash indicators (wipers, lights, heat/vent controls), and even installed a rearview mirror with map lights using LED bulb replacements. So much brighter and more reliable.

Amen brother! It took a while for me to get around to a full conversation, but one of the first things I did after buying my CJ5 was installing LEDs on the speedo cluster, and they still work great over ten years later.
