New to this fourm today found it while I was looking for a hard to find part for my 1983 ninety eight regency brougham hoping someone can point me in the right direction the part is the rectifier for the side opera lights its a blue 5 prong electrical part that is in the trunk on the left side my local G.M. dealer tells me it is discontinued thanks I am going to enjoy this site



Thus is the luminescent rectifier i am looking for thanks John.

 

Time to hunt junkyards, the only problem with that is all the older cars get scrapped and then clapped. Good luck with the hunt. You may try the parts wanted section and post up what you need.

 

I will try that thanks Tru Blu 442

 

Well I found a NOS relay from Saudi Arabia installed it has power to the relay and power to the wire going to the opera lights but they still don't work and all fuses are good

 

Do you have a Factory Service Manual with a wiring diagram? Since there's 12V at the lamps and they don't illuminate did you clean the bulb sockets and make sure they aren't OPEN?

 

My 85 has these lights as well. They haven't worked since I've had the car. I figure the easiest thing to do is to covert it to LEDs.

 

No service manual but I will check the bulbs the car only has 44000 miles on it all original and everything works except the opera lights thanks for your reply.

 

Here's a video explaining a work around. There is an inverter available that will work, but it's made for Sea Ray boats so it needs some modification. Also the video goes through how to test the inverter to confirm that's the problem.

 

Found one its NOS from all places Dubai and they still don't work so LED conversion might be the answer thanks for all the information appreciate it.

 

I'd compare the test results from your old inverter with your new inverter. Ordering any NOS parts from overseas would be suspect. I hope you didn't pay too much.

Good luck with the repair. 👍

 

If the bulbs are good, check the sockets for corrosion. Also, check the spring loading of the socket terminals.

 

Voltage at socket? If the bulbs are good, check the sockets for corrosion. Also, check the spring loading of the socket terminals.
