However, as cool as they look, I had to replace them with GE 3457NH/BP2 ... The LEDs were just not anywhere near bright enough for me at all. ... Book reviews

these may not work unless the vehicle is running as leds require a certain amount of power to work..also check the ground wires..turn on 4 way flashers and see what the lights do.. repost..

As for the horn, inspect the fuse and relay and most common it would be a bad ground wire or worst a bad horn due to corrosion. Horn will be located in the drivers side fender.
Thank you for using fixya.

1) You will need to open the rear swing door.

2) On the inside jam there are two torx headed screws (T-15's if I remember correctly).

3) Unscrew the two torx screws.

4) The light is now held by two mounting tabs (small spherical headed plastic sets that go through a rubber grommet).

5) You will need to pry the light casing off (easy pressure with a good size flat head screw driver will do the trick).

6) The light bulbs are twist mount settings inside the light casing.

7) Twist out the mount setting, change the bulbs, and reset the light mountings.

8) To put the light casing push the light casing back on and put in the screws. Everything else will work in reverse when it comes to assembling the whole unit.

Thank you for using fixya, and good luck

yes ..., there are 2 bulbs in the tail light assembly 1 with just 1bulb for the back-up lights and another with 2 elements 1is for your running lights and the other for the brake light if the running lights are operating and the brake lights are not then remove the taillight assembly to see if the filaments are both still connected to the other terminal or sometimes it will turn black also check your fuses if neither one works ...

3157

If you need further help, I’m available over the phone at https://www.6ya.com/expert/michael_00678fd4800d19c5

the problem is not the bulb it is the connectors the bulb is connected to...rebend them so they touch....its happening on all the 2000 jeeps...email me for any more [email protected]

There is a metal tab that makes a contact for power to all three bulbs. Remove the taillight assembly and check the contact.
