Rear Fog Lamps

[brental1]

These turn on when you press the fog button 2 times. When rear fog is activated, the button acts like this.
1st press, front fog
2nd press, front and rear fog
3rd press, front fog
4th press, all fogs off

These wouldn't be considered backup lights unless you turn them on while backing up, which is the main reason I started this project. I work off-road at cell towers and usually can't see much in the reverse cam at night, but I didn't want something that turns on every time I reverse, and I can't stand cheesy non-factory switches in my vehicles, so I used the built-in rear fog functionality. It works great for lighting up my towers, tools, trailers, boat, etc.

Was the rear fog icon present in your cluster? If not, did you find a way to add it?

Hi everyone, has anyone completed this mod? What were your findings? Quick question—were you able to get the cluster to display the rear fog light pictogram? I tried manually triggering mine with AlfaOBD, but no luck. Also, regarding the OE switch with its four different modes, what steps are needed to activate it?

Thanks in advance!

I've almost completed it. I found out, from Jimmy's reply and using the '10 second test' in Alfa that the rear fog icon is not present in my cluster. Seems it's only present in export clusters. The green, front icon does display in any of the 3 ON states. I've started investigating adding another LED in the cluster; but don't know yet if this is possible.

Wow! I finally have rear fog lights. They're really bright. They overwhelm the camera when you're directly behind the truck.

Looks great! Did you end up cutting your existing bumper pad? How did the lights mount up to it?

I did. I messed up a little on the first one. I though the lamp should protrude through so I kept enlarging the hole. Figured out that the posts on the lamp position it to be flush with the plastic.
Did a better job on the second one. They don't look bad; but I'm going to apply some RTV in the gaps.

Good job. I should have parts in a week or two and will install mine.
