97 Plymouth Neon Interior Lights Turn on when Braking

sounds like you have water in youre light socket. or the wrong bulb is installed.or a blown bulb.

Does any lights on the right side work? It sounds like the ground connection to the assembly is loose.

Have the alternator checked,it is most likely shorting out,or discharging.

bulbs

its not a bad job on a neon ,the fog light kit you will buy will come with a switch and the relay and wiring for installing them,they also came with a real good set of directions for doing this,if you need to get someone to help you with doing this,sometimes running the wires is tricky,but other than that the fog lights can be mounted in the same place as the originals was,and they look good,i sold my 97 neon and i had fog lights on it,they were after market but looked and worked excellent,with a little work and time anyone can install a set on any car,good luck.

Well, check the fuse box in the engine compartment...then check the fuse on your side panel at the end of the dash...last place, Flashers are located either on the bottom of the fuse block or on a module under the dash. They are replaced by simply pulling them straight out. Note that the prongs are arranged in such a way that the flasher must be properly oriented before attempting to install it. Turn the flasher until the orientation of the prongs is correct and simply push it firmly in until the prongs are fully engaged.

possibly a no spark condition check to see if your getting a spark if not replace the coil

ck your wiring?

Check your fuses.
