If you measure the lights that you need Vista will send you the exact lights for you unit. They are easy to replace since only 12v don't have to worry about getting a shock. I replace mine on my steps, they were square lights, and they fit right into the slot. So check the lights that you need and email them with this info and info on your rig. Make sure when u measure that u do an exact measurement done to the 1/4". Thought I would just round off my measurement but when I sent them the dim. Krista email me back saying they can send that but the rig had 1/4 longer one. Short story, got the 1/4 longer to match original. Like the previous note says don't buy from HD or Lowes for they are for 120v with step down inverter. Listed below is a copy of the email from Vista

light. I will quote you on that as well - it is a very small difference in
length, but it might be what was installed in your unit.
