They were involved in the prime mover or heavy lifter main rocket of the saturn IV program. Chrysler and Phillip's lighting also co developed electro luminescent lighting. This was light weight and very vibration resistant and used for backlighting the panels in the LEM and command modules. Chrysler also used this same lighting for the gage faces and illuminating the gage pointers on new Yorkers, and imperials from the late 50s thru the early 1960s. An EL dash looks great lit up. Last car they put one in was the 1967 charger. The EL panels are built so well they still function great 50 years later. Power supply takes 12VDC and flips it and steps it up to 280 to 300VAC to light the panels and pointers
