Vehiclelight.com 4" Flanged LED Red 44 Led Stop/Tail /Turn Lamp
Pros: Easy to install, wiring easy as well
Cons: no instructions, no dimensions, no wiring diagram for pigtail
Comments: Easy as pie to install, once you get over the fact that you have to cut your tub. I guessed on the wiring and got it the first try. It uses a 3 wire pigtail that comes with grease on the connections. Seems to be sealed from the elements very well. PIGTAIL WAS NOT INCLUDED. It was only like $5 or so though.
I used a 4.5" hole saw to cut the holes...It may have been 4.25"...I Cant really remember right now. I just took the light to home depot and matched up. I paid $34 for the hole saw though.
Stuck some RTV behind hte left light. I forgot to do it on the first one (passenger side.)
I used 1/8", 1/2" hold rivets, with washers on inside and outside of tub.
