If they are 194 lamps, (or any other for that matter) it's an easy matter to change out the bulbs to LED. I did some with a 5 LED bulb from Super Bright LEDs to replace 194 lamps. The sockets may need cleaning and a light coat of dielectric grease to help prevent corrosion. If you are having wiring issues, you will have to remove the fixtures and reseal them upon re-installation with butyl.
