Left side, toggle switch on bottom, I think is for the blinkers? What did the stock one look like?



Right side, here you can better see the red colored things that appear to have been melted? What are these? Are replacements available?

BTW, Loud...
The problems that can cause melting of those lenses are ....
#1 Wrong Bulbs...(too many amps)
#2 Voltage Regulator Failure (usually, more than about 13 volts is too much. Often that will also start burning out the smaller dash bulbs.
