I'll start on the circuit today or tomorrow. In the spirit of Steinmetz' divine discontent, I will look at eventually setting up a current limiting dimmer for the LEDs. It wouldn't work on the map light LEDs as they just have the trigger line and are entirely internal to the RV mirror. Putting it in...

There is a much easier way to do this. You need to find the common location of the ground point for the courtesy lights. Make sure both, all four, or whatever number of doors you have are connected to one side of the wire. Now disconnect (cut???) the wire so you have one end going to the lights, th...

I am looking to build my own LED tail lights for my car. I have two questions: First, where can I get dual intensity LEDs. I see a lot of new cars that have LED tail lights that illuminate at one light level for running lights, and then when the brake is applied, they go to a higher light level. Se...

Greetings (No first Name Supplied), Got a schematic from a guy that supposedly does all that. I haven't cobbled together circuits in a while and never with a 555. How does it look to you? The text doesn't match the schematic. Take a look at the LM555 datasheet to find the error. Using the LM555 (or...

Hey all. I have a car with courtesy lighting circuit that is always hot. When the doors are opened it grounds the system and the lights come on. I spliced into the car an electronic rear view mirror with a separate line and a high side trigger to fire the maplights in the courtesy lighting circuit. ...
