When drinving at night, when you step on the brakes head lights will dim.
I have a 2004 Dodge Neon and recently replaced both the battery and the alternator. I still get the dimming whenever I'm driving and step on the brakes. I sometimes hear a popping noise in the radio also. What is causing that??

Could be a bad battery but I suspect your battery cable is either loose or corroded or dirty. Before you pull the battery disconnect your battery cables and clean them both ends and when you put them back on make sure you have good connections and tighten good.If that does not work pull your battery and get it tested at a battery out let . they should do that for free.
Was any of the brake light bulbs changed recently, the wrong type of bulb may be used causing a short in the socket, and making the rest of the brake and signal circuit malfunction. I no bulbs were recently replaced, start with checking for corrosion in each bulb socket, signal and brake bulb sockets. Let us know what you find
Sounds pretty "cut-and-dry" to me. You need to charge or replace the dead battery, and make sure your battery cables are CLEAN AND TIGHT and then check to make sure your alternator is charging correctly.
what you are seeing is the bright filament on the bulb working, the tail light bulbs have two filaments in each bulb,one is dim and one is bright,the bright one is to the brake and turn signals,that way when you step on the brake with the tail lights on the same lens light up brighter to warn drivers behind you.. you need to check the fuses in the car for tail lights first,see if your plate light is on that will tell you the bulbs are just blown
on a neon the cam sensor is located at the drivers side of the engine on the end of the head. it mounts directly over the end of the front camshaft. it is about 3 inches wide and about 2 and a half inches tall. its made of black plastic and has a wire conector in the back of it. these very comonly leak oil so be careful of the o ring and cleaning the mounting surface.
Brake lights draw fairly hefty current; about 50W total (4 amps) so some dimming wouldn't be serious but you might want to remove and clean battery terminals at the battery and the ground (negative) cable that normally is connected to the chassis and/or the engine block.
A low-cost Chinese digital multimeter (< $20 US) would help you locate this kind of problem - and many others around home too.
You don't need to be an expert to make use of these and they all come with some kind of Chinglish instructions that sometimes even intelligible.
You can buy these at Radio Shack in the US or about any chain auto parts store.
With one of these and a helper to sit inside you can check across the battery terminals directly, then between the clamps, to ground etc. to isolate the source of the voltage drop.
