So i had this idea to add LEDs to the engine bay of the 600LT MSO. Saw a post on someone’s 720S and looks cool. So..... some 10 hours (*about 2 hours install and 8 hours figuring out the wiring and calling my tech from McLaren for advice..... etc....) and boom. Really happy with it. Fully Bluetooth, any color , works via the phone... and ..... total reversible without damage!. Total cost - about $80 in parts .. (thank god I don’t charge myself by the hour!). The kit... is the OPT7 engine bay kit (although... quick hint... the Opt7 grill and opt7 interior are the exact same kits! ). Great for shows.... a little personal touch!
