No brake lights but i have taillights in MJ Tech: Modification and Repairs Posted January 27, 2016 Have you checked the brake light switch ? It's towards the top of the brake pedal with two wires going to it . http://comancheclub.com/topic/38850-fixed-no-brake-lights/page-2 yeah I have checked the switch because I didn't have lights once before at that was the cause of the problem. there was a wire disconnected. so a few days ago when I noticed I didn't have lights I pulled over and checked that right away. everything is all good on the switch as far as I can tell.
