Like Danny, I installed a reverse light under the rear clam shell. Mine is run to a toggle switch under the dash though. I have it connected to my blue high beam light to remind me when it's on. It's very useful for backing up at night, @Napa Paul. I live in the country and it gets very dark in the woods around these parts.
You can also see my extra brake lights behind the grilles. I did make a thread of that upgrade. https://www.speedsterowners.co...itional-brake-lights
Ed is also installing a reverse light on his Thunder Ranch.
