So-called puddle lights, designed to light your way when you open your car door, are commonly found on luxury vehicles. Most of them also project the automaker’s logo onto the ground. You can now get the same type of LED light display for almost any make, including high-end models (Ferrari, Bentley, Mercedes-Benz and Jaguar, to name a few) as well as for Chevrolet, Ford Toyota, Honda, etc. Each unit attaches to the inside door panel using 3M adhesive (no drilling required) and will automatically light up whenever the door is opened. Power comes from three AAA batteries, so there’s no wiring to do. Order for $13 per door at amazon.com.
