    Opera & Cornering lights?

    From what I've seen, it seems like the pillar opera lights and the cornering lamps does not work on 90% of all older Cadillac's, including my 89 Brougham. Anyone here who got functional opera or cornering lamps? I guess you just have to change the bulb's, but since the majority not have done that i guess they are hard to get to?

    When I bought my 86, the cornering lights didn't work. Replaced all the bulbs (which were burnt out) and nothing. Turns out the fuse was blown. And it is a PITA to get to as it is on the top of the fuse block.
    Also, oddly, if you have a burnt out turn signal or running light, the cornering lights won't work (but then your lights work weird in general).

    No expert here, but I've always found that the cornering laps on these cars work just fine if put a fresh bulb in them. The opera lamps are a different story. From what I've heard on some Buick forums, there is a metal strip within the lights that goes bad. I've seen some successful threads of people who of taken them apart and made custom metal strips to replace the originals and have gotten them working again.

    Re: Opeara & Cornering lights?

    I ended up finding an older style Opera Lite that had the same footprint as the electro-luminescent type but were the bulb style. The e/l fixture was just plastic but the older ones were chrome. The E/L tape can still be had from ADAFRUIT INDUSTRIES if you want to go that route. You had better check to see if the inverter in the trunk is any good before going that route because that will be an extra expense. The light have a 110v line and a 12v going to them, you can just cap off the 110v line and use the 12v for the older lamps.

    Did your car have the B pillar or C pillar opera lights?

    ^The DeVille uses a totally different style. The Broughams had EL tape to power their opera lamps, but because of the type used, very few still function, due to ultraviolet exposure.

    We've discussed this aeons ago. My Opera lamps work flawlessly and will most likely outlive my. This is because I have determined how to dismantle them and have replaced the EL tape inside of them.

    As for the cornering lamps, I will be honest, I have NEVER heard of someone without functional cornering lamps.

    Re: Opeara & Cornering lights?

    On my 80 coupe, both opera and cornering lights work..
    now it was said (cadillac kevin) that if your blinker or running light is out, it won't light up (cornering light) that is not true. On mine it would. When I first got the coupe 15 years ago, one side of the cornering lights work and the other side didn't. Both blinkers worked and flashed, cornering light would light up to the side that worked with blinker flashing, but when switched to other side, blinker would flash but cornering light didn't work. Bulb was fine. When I received my eletrical troubleshoot manual it says, if one side operates and not the other side, it is your cornering switch, which is part of your turn-hazard switch assembly. Since at the time I had my other 80 Brougham coupe, I removed the cornering switch from that car and spliced it in and presto, the inoperable side worked and has been ever since

    The opera lights have an hour life but instead of dieing straight out they just start getting dim in different spots until they don't light at all. UV is a double whammy that makes the plastic they are made out of dry out and crack.

    That's the biggest problem with them when they don't work and it used to be pretty common. Other GMs with cornering lights have the same issue.

    I agree with you on this, I really do, because all science indicates this, but in hindsight of all my time living in Nevada and Florida (the places I live presently and have for a decade now) I have never found cracked plastic on a car that was caused by ultraviolet exposure.

    Still, I agree with you. I am just fortunate enough to have never experienced it.

    Really? Lots of cars get lenses that go brittle with hairline cracks all over or yellowed, or pittled from the plastic being eaten away from the sun. Cars from areas like those are also prone to rubber seals that crack or get rough from their surface being baked away or shrunk.

    The clear lenses of the opera lights stay good but when you take them apart you see that it's the tape inside them that can go yellow and break apart and oddly enough happens more to ones that are already failing rather then ones that still work.

    I don't think there's a fuse, but I could be wrong. I don't have my manual with me plus, I'm at work..
    If it were a fuse, other stuff associated with that fuse will fail. check your switch as I mentioned above and go from there.
    I'll follow up in the morning if there is a fuse or not.

    Re: Opeara & Cornering lights?

    Ijust went out and had a look. there is 10amp fuse which are for both the parking and the cornering lights. But since my parking lights do work, i think we can assume that the fuse is intact. When it comes to the opera lights, i'm gonna dissamble them and see if there is any voltage at all coming to them, if it is i will be ordering a new set of EL tape and fit them in.
