Grab Bar Light Diode

I recently heard that at a small rally somewhere recently there was someone who was replacing just the diode in the grab bar light instead of replacing the whole pigtail. Would love to do the same but trying to find out what diode and where to get it. Many thanks for any help.

A LED needs a resistor wired into the supply so you don't over power it. For example:

This LED 5mm High-Brightness White LED (2-Pack) : LEDs | RadioShack.com would need a 390 ohm resistor in the circuit.

Find a LED and its power requirements, figure on 12.7 v supply and plug into this calculator: LED calculator for single LEDs

You'll soon be lighting up everything that doesn't move in your RV!

I did mine last weekend with that exact diode, and a 670 ohm resister, also available at radio shack. You'll need some shrink tubing and soldering skills.

rvhappy.......Check with Fleetwood first for the replacement LED. I went through a whole ordeal to get/make the right diode for my handle and later found the replacement assembly from Monaco was only $9.00.

Done it myself. However in my case I had to do it twice as there was another issue.

First replace was a generic diode from "Stock" (Box of assorted diodes) joy was not mine as it was short lived.

2nd try I measured the series resistor.. Way too small. so I got a JUMBO LED from Radio Shack, this is a high-brightness, higher current unit, and it required I ream out the hole in the reflector a bit.

I also did the math based on 14 volts and pickd a new resistor (From stock, box of assorted again) to put in.. Here is the math.. Forward current in mA/12 (Answer is in K-ohms, I got 0.6 as I recall or 600 ohms) if you like you can use Current in Amps'/12.
(Gives direct value, use next LARGER standard resistor)

That's all there is to it.

De-solder original resistor and replace (If necessary)
De solder original LED and temp insert new one (DO NOT SOLDER

Apply power, if it does not light reverse diode and try again, When it lights, Solder.
Home is where I park it!
