This thread is looking a little stagnant so I will post my new change. I had installed aux. backup lights a couple years ago to allow me to see while launching and retrieving my boats at night. I used regular tractor lights that were common at any parts store. Recently the left side bulb burned out ,it is three years old but has an hr. of time on it at best. I decided to upgrade to some LED'S off E-Bay and can't believe how much brighter they are. This shows the difference I did change both.
