Replacement for factory type. Kit is complete with housing, lens, bulbs, and has 12" wire lead connector. Measures 5-3/4 wide by 6-3/4 wide by 3 deep.
Not sure who thought it was a good idea to package the hardware inside the taillight so that during transit metal nuts and bolts can get jostled around and break lightbulbs. Cause that is exactly what happened to my box. Luckily I had an extra bulb to replace it with instead of worrying about a return and replacement set. If you order this, don't be surprised to have a broken light bulb. Be surprised if its not broken. The system works great once the bulb was replaced and it was an easy install with a single connector and a few bolts through the tub. One note, the factory taillights on my 78 CJ5 were mounted with a self tapping screw. The replacement bolts were a little bigger than the factory screw hole that was left after removal. I had to enlarge the three holes with a drill bit, but nothing significant
