josh the front and rear brake both have a micro switch that puts the brake light on when you pull the brakes on,you can start the bike by pulling either brake if they are both working and they should be for safety and for an mot too.the two switches are screwed into the brake lever assemblys under the top panel at the front on the handlebars and have two wires on each switch,the switches are about £5 each.the speedo instrument bulbs are totally seperate and use small capless bulbs that lock into a plastic bulb holder and twist into the back of the clocks on a flexible circuit board
