Replaced the halogen bulbs for LED & new HID low beam bulbs.

[MrMonte]

Replaced the halogen bulbs for LED & new HID low beam bulbs. On my 2018 Yukon Denali with 132K miles. Also installed the harness that allows the fogs to stay on with the high beams on.
Was pleasantly surprised on how easy to work on. Took about 30 minutes to replaced all bulbs front & rear. The harness took about 30 seconds to locate & install with only knowing it's under the dash.

I like the all on feature.

Did the “all on” harness throw any codes? It’s a pending install for me but I’ve read some reviews that have indicated random issues such as the horn bizarrely becomes disabled and codes related to lighting are generated.

I used this one on my 2010 and 2016 Suburbans, locate two wires, feed into slots, clamp down. No issues in years.

If I may ask, what was the light bulb numbers for the backup lights and also license platelets? And by changing out the license plate lights, do you get a glaze or a haze from your backup camera? Thank you

no, I guess maybe it could depend on what you install but the fleece doesn't cause issue's at all, fogs work like normal or come on with high beams or flash to pass

Fleece All Lights On

Fleece Performance All Lights On module allows for fog light functionality when high beams are enabled. Application-specific design.

I can't use the 6 high on the silverado because it has projectors, high is just a actuator that moves the bulb housing

No glare or haze on backup camera. These are the reverse & license plate bulbs I used.

Not a fan of putting LED drop ins in housings not designed for them. but i won't lecture you on that. i do like the plug and play 6 high harness though, the older fleece set ups were great, but i never really liked how on the K2s it's essentially a dual alligator clamp to cut the wires and splice them together. I get it that it's cheap and simple, but i hate damaging wires to do something, which is what the fleece one does on the K2s. I'll be snagging one of those harnesses for sure

No issues on my 2020 Yukon doing this.
