This replacement Cadillac Deville tail light is just what you need to get your Cadillac in good looking form again!

This Tail light features the following specifications:

  • LH (driver's side)
  • Replaces dealer part number: 5978125
  • Injection molded plastic
  • DOT (Department of Transportation) & SAE (Society of Automotive Engineers) approved
  • Direct replacement
  • Quarter (1/4) panel mounted
  • Does not include bulbs or wiring

We have noticed that there are many inferior quality Tail lights on the market. We have researched other tail light manufacturers and are only selling what we believe to be the highest quality, best fitting, aftermarket tail lights available. So don't be fooled by cheaper made imitation tail lights. Go with superior quality!

This Cadillac Deville tail lamp is a great replacement and has good cost savings over a taillamp from the dealer.

Bulb Note:

Unless otherwise noted, our lights do not include bulbs, though occasionally lighting manufacturers do include bulbs in the lights. If you happen to receive a lighting product (Headlight, Tail light, parking light, fog light etc.) that comes with the bulbs, the bulbs are not covered under our warranty. Our warranty applies only to the light assembly.
