Hi guys I installed non can-bus led brake light bulbs in my coupe, I wanted the faster response on the brake lights. I wired the resister on the brake light circuit. The resisters get quite warm so I didn't wire resisters into the running lights. The warning dash light only comes on when the running lights (head lights) are on at night but not when I hit the brakes during the day with head lights off. This keeps the resisters cool as they only heat up when I hit the brakes.
