Led brake light

Anyone have an issue with using LED 3157 "bulbs", to the point of...jeep on, lights off, apply brake...brake lights go on...and so do the dash, hvac, shifter n 4wd lights...cant be just me. But 23000 posts to search didnt turn up an answer that was suitable.

Check your ground at the lights. I'd even go as far as adding a new bonding strap from the tub to the engine block. LEDs don't work like a regular bulb and I'm thinking that since many dash clusters have "Bulb out" warning indicators of one form or another the change in the ground resistance is tripping it up.
