Help identifying an LED and also an application question

<< < (4/4)

TT_Vert:
Thanks, given the mirror is in many pieces/boards and to get it apart to measure voltage while still assembled it would have been difficult to measure the actual voltage while emulationg door open so I don't know what the input voltage was.  Given it has 38 ohm resistors for  each of the 3.3V@20mA LED I'd have to assume it's under 5V but I don't know for sure.  I did keep the light powered on w/ 3.3V (which is about what the led that was on that circuit was probably getting) and it didn't get over 151 degrees while on for about 20 minutes so hopefully for this application it won't get near that hot.  What do you guys think of that thinking?
