Center point is "+", the body is "-" Reverse from standard D.O.T. Not the sellers fault. it's mine for not checking the RV before ordering.I guess center negative "-" is not as common. and that's what my RV...

Rather weak light too. Not worth returning.

I don't think it mentions in the ad that these are Amber colored LED lights. I thought they world be clear. They are very difficult to install in my side marker light sockets on my class a motorhome as you have to press them in and turn them to get them to lock into place but the entire led bulbs part spins when you try pressing and turning it to lock in place. They are also much more dim than the original bulbs and fit loosely in the socket. Cheap price though and they do work.

none of them worked for me

I believed these bulbs to be much large than they are, and they are not the bulbs I needed. It is my fault for not reading the detailed description down further on the item that shows the dimensions, but it would be helpful in the product images to have one that shows the dimensions (like most bulb products do). Or in the description at the top of the product page. For that, I've deducted a star, but I have not way to judge the quality of the product itself.

These make such a difference in my truck. I could ask for a better quality of bulb that is brighter than the yellowish factory ones. These are very easy to install. Honestly, I had a harder time taking the factory ones out. I do recommend these if you are replacing your interior bulbs.

These are hard to find in LED versions at local auto stores. The red coloring matches the other LED dash bulbs. These are a little longer than standard incandescent bulbs, so double check you have room in the housing or lamp assembly.

These worked good for my side markers, but I had hoped they would be a little brighter than they are. I agree with other reviewers who want actual product pictures and dimensions in the ad, so people can see the amount of light and can decide on fit for their application.
