Honey, I retrofitted the car's interior lights with LEDs

A dead battery in my SO's car got me thinking about ways to reduce the chance of that happening again – to either of us. Why not replace the interior car lights with LED versions? Sure enough, hitting the Web revealed gazillions of choices. Car interiors commonly use wedge-base bulbs, and festoon bulbs, the name given to cylindrical lamps with a contact cap at each end. Who knew? Being a cheapskate, even the reasonable prices I was seeing were more than I wanted to spend. After all, how many times have we all ended up with junk when trying a relatively new product category? Sometimes paying more results in better product, but often not.
