Hi all, I fully admit complete ignorance about LEDs, apart from the great ability to emit light for less energy draw. Since I installed an Alton generator on my C Rapide, I felt it was time to switch to a 12 volt system. I ordered an LED circuit made specifically to fit inside the Miller "STOP" light receptacle and was about to install it when I noticed on the package a box checked "6 volts". Unfortunately, the company I bought it from appears to have folded - or at least the website (bulbsthatlast4ever.com) has disappeared. My question, therefore, is: will this light work in a 12 volt system? Will I rapidly destroy it? Does fitting a resistor in series make it suitable? Any other way I could make it work? Thanks in advance, Paul.

The simple answer is yes, but,,,,,, it's best to measure the current the panel draws on 6 volts first. Then you can calculate the value and power rating of the resistor.
Another way is to put a small zener in series with the existing setup 6.2 volt 5 watt will be fine in 99% of instances. Cathode (bar marking across the plastic of the zener) must face positive supply. It can be in either line.
you would be able to get one at a Radio Shack etc. cost about $1.00
Running a resistor or zener , to drop 6 volts , does not appear to be very efficient And Kind of defeats the point of using LEDs as a power saving strategy . How about using 2 cheap buck converter boards , 99cents each , shipped from HK , instead ?
Before doing anything , Check the light- board , with your best glasses , for any specs or documentation that may be printed on it .
