What is this light

[Jennifer Fuzion 414]

I've typed this message three times and this stupid cloud fare security thing had cancelled it several times, finally had to switch to Safari.. it seems like each time I try to post here that locks me out.....

I made a nice funny post and lost it all due to that stupid thing...

I'm not retyping it again... can someone tell me what light that is, is it the reverse light, thank you all

Clearance lights required by DOT

Turn the parking lights/headlights on and check should be red light like on the corners

It looks like a white LED light to me, more than likely a REVERSE light. plug into the truck and put the truck in reverse. Common on toy haulers.
