Hi! I need your help on some things i would like to do in my car. I tried trying to calculate the stuff needed but got lost in the process. Here are my projects:
Project 1. DR Light / Blinker
I installed a fender light on my car. I would like it to turn on with the Daytime Running Light (a little bit dimmed) but still function as a blinker (bright). I was suggested this schematic: (The left one)
**broken link removed**
The voltage source is the car alternator: 12v-14v
The load is a 12v/5w bulb
1. Is a 1N4001 Diode ok?
2. I initially used three 5w/10Ω ceramic resistors in series. They got too hot to touch. What would be a better one?
Project 2. LEDs
I have a couple of super bright blue LEDs that i got from an automotive store. They are supposedly plug and play. (no resistor) Though i'm sure a resistor will help prolong its life. The box had no information available as to its forward voltage, etc. What would be a good guess resistor value?
Thanks in advance!
