Troubleshooting LED Single Wire Clearance Lights

Question:

I just swapped out the original tear clearance lights with 12v LED ones. nothing works now. If I didnt get a good connection on just one light, can that cause all 4 not to work? Scratching my head and feeling frustrated. Any ideas? One wire lights also. Used butyl putting to mount them on the side of an travel trailer. HELP

The reason your single wire LEDs aren't working is because you aren't using a ground. Most single wire lights like the Amber Clearance Light with Stainless Steel Hardware # 47-99-006 will have a separate ground like in the mounting hardware. The Thinline LED Clearance and Side Marker Light # AL91RB you asked from will ground through the mounting bracket # A91BB.

The mounting with butyl tape is the issue. You need to have a ground connection for your clearance lights to work.
