There could be a few things that might be cause your malfunctioning rear sider marker light. You will have to examine a few thighs to determine that issue. Most light today a sealed units that will have to be replaced in full instead of replacing a bulb.
First, you will need to remove the light assembly from the side of the trailer and inspect the wire connections. Some of the light will have a removable plug that connects to the back of the light housing. if you have this, then make sure the plug is securely plugged in to the housing. If you have just wires coming out of the housing, then inspect the wires for any damage that could be causing the light to not work.
Using a tester like # PTW2993 on these wires can tell you for sure if you are getting power from the vehicle back. If you a power signal is detected, then most likely the light is bad and needs to be replaced.
If the unit is sealed, we have full replacement lights, like # MCL63AB. However, these lights do come in various sizes so you will need your current light's dimensions to find a replacement.
I have attached the product page that will list all the clearance lights we carry for you to review once you have found your correct size.
