Pop the box 1/2s apart and let the side that faces the seat droop. Inside it you will see a bunch of small screws and plates. Take out the screws that hold the center assembly in place and gently, very gently or you will disturb/lose the switch springs, lift out the assembly. Clean the metal parts with a pencil eraser, wipe clean, reassemble.
Piece of cake.
But, check both bulbs first, the bulbs can be vibration sensitive and have broken filaments. The front set can be replaced with a generic 1157 bulb, the rears with an 1156, unless Suzuki in another flash of infinite stupidity switched to the modern versions with a plastic base...
I think they are after market 1156&57 do not fit bought all new OEM bulbs and none fit.
I just bothers me and looks like crud. But I will try to fidn the bulbs and hopefully that will be the end of it.
