What is a little brighter single element bulb?The standard bulb is an 1157. A brighter bulb is the 2357 but it doesn't last near as long. Make sure that the socket and terminals are clean and brighten with a little steel wool or fine sandpaper if necessary. A little dielectric grease on the bulb base helps as well.
LEDAny recommendations for a bright tail light bulbs?
I believe most of the auto part stores have them now.Where to buy LED lighting? O'Reilly autozone advanced auto napa? Ebay?
NoWould LED bulbs cause it?
Key doesnt matter. Hit a live positive with anything grounded and you get sparks a flying. That big lug on the starter relay is always live. Now if the ground cable had been disconnected then you would have no sparking as the circuit you created is incomplete. Electricity is always looking to complete the circuit. And when it does work is gonna happen. Starting the car or melting the wires,electricity doesnt discriminate.I have two threads about this in error. I was checking the oil in my car and hit the dip stick against the battery terminal (closest to the firewall - positive?) and it sparked. The keys were not in the ignition so I thought it was strange and realized maybe the battery is not grounded.
