I cannot find my photos but here is the LED I purchased:
LED Lighted Assist Grab Handle Replacement Bulb Illumagrip RV camper Trailer | eBay
In my case, when I took off the grab handle the plastic would not separate from the metal end. I merely used a long 1/4 inch drill bit to drill a hole from the side of the motorhome into the inside of the cabinet on the other side of the wall. (I had to drill at a 45 degree angle because the cabinet was back about 6 inches. I was able to access the inside of the cabinet by taking out all the 12 volt buttons just to the left as you enter the motorhome. I merely pushed the LED down the inside of the metal grab handle and fed the wires to the inside of the cabinet. I then found the switch that turned on the outside light and tapped in to it for my power source. (I have hear about other people dropping the line down to the little light under the motorhome steps.) Now whenever the side light is on, the grab handle is on. Really cool.
Let me know if this helps.
