Looking to replace halogens with LED for specifically headlights/fog lights and possibly all lights on the vehicle. Best brands? Was looking at LASFIT? They sell complete set of lights.

 

Seems like "best" may change from month to month if you are looking at YouTube reviews ... but, I ended up installing the TechMax brand off Amazon for Lo (mini H11) and Hi (mini 9005) beams, and Sealight Force (9145) for the fogs several months ago. No issues, no flashes from other drivers. Lifted truck, so I did aim them down a bit to more or less match the level of my wife's Tahoe lights (against garage door).

I used Hikari H11s in my prior car's projector foglights, and they worked well too.

Last Christmas, I installed a set of Diode Dynamics SL1 in the low-beams of my wife's Tahoe (projector halogen), my daughter's Honda (projector halogen), and her boyfriend's F150 (2016 XLT halogen). Those have been great too. Decided to try "budget" bulbs for my truck when I bought it earlier this year ... all three pairs cost about the same as one pair of the DD.

The iJDMTOY and Yorkim brand LED light for the other miscellaneous sizes for interior and exterior lights have worked well.
