Time for an update on this guy. Since the quarentine I've actually had a ton of work - and a family trim in there too - plus my folks are moving to my property right next to Baja Broncos Unlimited...their house will be 10 feet away! Hahha. So not much time for Colt other than to drive around block and sit in and research.
Anyway, I found the correct taillights - which was no easy task. Got lucky. So I knew the plastic lights on Colt were mid to late 70s and cheap plastic. But early photos of it showed a cool looking metal chrome base light. I was looking at early Porsche, datsun, british car whatever...nothing matched. I met a friend at a swap meet shortly after and while trying to find him, wandered into a spot. A guy had a ton of random stuff on tables...you know that guy at the swap I'm sure.... anyway, i see the light, pick it up and ask how much. 5 bucks. Perfect. Now I had a part number, etc, and turns out it's a trailer light from the 50s and 60s. 6V and single element. But it's a match. Found some NOS and some spares and the NOS are on Colt now. The worst spares, I cut up and welded some 1157 sockets in so I can swap those in and have brakelights and turn signals. Here are some pics of the light swap. Not much else other than more research and chatting with folks. Will try to post more fun pictures of interior and underside too. Still my favorite Bronco.
