FWIW Here is my EV LSV with the Seizmik light bar, hood rack, outside rear view mrrors and OEM roof with the OEM glass DOT windshield (Lock & Ride clamp on). No problems. Routed the wiring up and over the front cross bar, down the inside of the passenger side A-Pillar and to the under hood compartment thru the A-pillar hole in the cowl. Seizmiks are attached to the A-pillar.
I used the Superbright LED dual waterproof lighted button switch wiring harnesses for the lights instead of the Seizmik harness. This allowed me to isolate and switch the floods and the spots separately (better usage ability and less current draw). I ran the wiring across the cowling and mounted the relays on the left frame horizontal cross bar next to the 12v auxiliary bus bar. I power off the winch batteries.
