Exterior Light Set for the 97-01 XJ
1WL-XJF Turn Signal Set (non-Cree, 3030 Chips)
1WL-XJE Brake Light Set (non-Cree, 3030 Chips)
1WL-XJD Backup Light Set (non-Cree, 3030 Chips)
DOES NOT INCLUDE RELAY for turn signals.
Look for an EP27 Novita brand relay at local or online parts stores. Test the relay with stock lights before installing LEDs. It will help with troubleshooting if there are any problems with the install.
See the turn signal set page before ordering. These lights are not compatible with 7-pin trailer lights or any type of trailer brake controller, as far as I am aware.
