Just wanted to draft this up now that I’ve got the Cali Raised 32" Dual Row 5D Optic OSRAM light bar installed in my Stealth Bumper. The fit was perfect, brackets lined up exactly where they should and it sits clean and flush behind the bumper opening. Couldn’t ask for a better match. I wired it into the factory aux switches and it works flawlessly. Everything powers up smooth and it’s nice having it tied into the truck without adding any extra switches. If you want to see how I did it, here’s my post on wiring to the factory aux setup: Factory Aux Switch Write-Up The light output is wild. It throws a ton of light down the road while still spreading wide enough to cover everything in front of the truck. This will quite literally turn night to day.

Soooooo, I just took my new Tacoma to the dealer for a check engine light that came on for the grille shutter malfunctioning, along with several other warnings on the dash. I took a photo of all the warnings that came on. My dealer has ordered I believe a whole new grille shutter assembly to fix it. I will keep you all updated on the fix, hopefully in the next week or so when the part comes in. The good news is that the vehicle was totally drivable. It just randomly came on.
