Cadillac Seville Tail Lights
When maintaining Cadillac Seville tail lights, there are many bulb options to choose from. Each bulb has advantages and limitations to consider. After changing the bulb and if the lens is in good condition, a clear, the right protective cover may increase the tail light's lifespan and save on future maintenance.What is the difference between LED and halogen bulbs?
Rear lighting can be either LED or halogen. Proper handling is important, so be careful not to touch the glass part because the oils from the hand can shorten the life. If possible, wear latex or rubber gloves.
Halogens have been the standard bulb for years, and most vehicles on the road use them. They are readily available and relatively inexpensive. Halogens shine a yellowish tinted light. The beam given off by a halogen projects out directly behind the vehicle. These bulbs have a lifespan of approximately 500 to 1,000 hours.
Bulbs in some Seville tail light lamps can be switched out to LEDs. LEDs are not as inexpensive as halogens, but the tradeoff is that they have a very long life when compared to halogens. LEDs can last for 50,000 hours. They give off a white glow, and their illumination fans and spreads out in an orb shape.How do you change a rear bulb in Cadillac Sevilles?
The tail lights are accessible through the trunk. You may need a wrench. Check the owner’s manual for the size of replacement bulb.
- Open the trunk and pull the trim away to access the back panel. There will be three wing nuts. The nuts may loosen by hand, but if not, use a wrench to free the light fixture.
- Gently rock the tail light out. To open the bulb sockets, press down and turn. The bulb should pull out.
- Change out the bulb and reverse the process to replace the tail lamp fixture.
Covers on Cadillac tail lights can protect them from rock chips, UVA clouding, and scratches. The covers are made of a pliable clear urethane, and once applied, they become a tough permanent shield.
If you want to create a custom-looking tail lamp without changing the entire fixture, there are hard plastic carbon fiber cutouts that attach over the outside fixture to create patterns of diagonals, stripes, flames or other customized shapes. The fiber cutout lens covers are available in black, white, smoke and custom colors. These covers provide some added protection but not complete coverage like the urethane shields.
