OEM housings on these come with a Single bottom Halogen foglight and a 'dummy' section up top....so he purchased and OEM Upgraded housing that had the top section as an option as well.
Then I cracked those open and retrofitted a Baja Designs S2 LED Pod in there.
This will be 100% independent from the Volvo's gnarly can-bus system...so it won't even know they are on the truck...which is a good thing...
They'll also provide the driver with an additional 4200 lumens! That'll do the trick!
