Replace burnt out tail light bulb

[Spaceace]

I have a burnt out tail light on my Rockwood 1640.

Does anyone know the bulb number for this? I'd like to have a replacement bulb with me when I go to install it and save an extra trip.

I haven't found anything online on how to replace the bulb. Is it easy to open up the tail light and replace?

Thanks in advance!

It's an 1157 bulb. I replaced my incandescent bulbs out with LED 1157 bulbs I purchased at Walmart, which are much brighter and effective.

I also replaced the tail light bulbs on my A-frame with 1157 LED replacements, bought at Walmart. My goal was to reduce the electrical load from the A-frame when towing and running the fridge on DC. Be forewarned that turn signal flashers don't always work correctly with LEDs because of too little current draw - mine had no problems, and I suspect newer vehicles have no issues.

On my A-frame, the tail light lens is removed by prying the side over a black plastic retaining tab. The clearance lights have bottom slots a small screw driver will fit in to pop the lens out. Very seldom are there screws; it's usually a tab retaining system of some kind. Study before prying.
