Changing Opera / Coach Lights Bulbs (Regal Limited Post 27 of 27)

Coach lights use electroluminescent elements, so there’s no actual bulbs to replace.
An inverter is used to power the opera lights.

These lights come on when you turn your regular lights on.

If these lights stop working, your inverter is probably bad, and needs replacing.

corner and opera light, RARE options!

CLOSE UP VIEWS OF THE OPERA / COACH LIGHTS:

.

There are aftermarket versions of coach lights / opera lights available, that use bulbs.
You can find these available online, or check ebay.
The downside, is that they don’t really match the style (or shape) of genuine GM / Buick coach lights (so if you want to keep your car looking factory stock, it’s not recommended to install these type of opera lights).
