Rebuilding A Federal Twinsonic Light Bar

This Twinsonic was mounted on the rear of an ambulance. It ran rough and was very dirty. I tore it down to the frame, cleaned and degreased everything and rebuilt it. The bar required new wiring, bulbs, and marker lens as well as lots of cleaning and polishing. Below are links to more content on my Facebook and other social media pages, as well as products that I use and recommend for refurbishing light bars.

Just from the way it's built I would say this was on the back of a box ambulance

[@thomasp942]

Yes, I'm pretty sure that is where it was mounted. Unfortunately, I do not know what actual unit or company it was with.

@@thomasp942 The three red clearance lights is a dead giveaway that it was on the rear of a unit I mean it could have been unlike the general motors panel van like support vehicle but with the light I would say more ambulance

[@emtffzartman666]

That thing looks so good!!!

[@NightLateRambler]

[@thomasp942]

Thank you! 😊

I imagine that spotlight would be vibrating a lot being mounted to the thin sheet speaker cover.

A bit of amber and blue towards the rear would have been awesome!

This looks like a lightbar used on a cop car in Tijuana. The DIY stuff makes it look rinky dink
