The starters can be found as a little diode (looks like a small light bulb) connected to the bulb sockets via two copper leads. Always unplug the unit and take proper safety precaustions. Installation is as simple as removing the existing two leads with small needle nose pliers and inserting the new starter. Repeat this procedure for the other starter. FYI, starters have a burnt look when new.

These spare parts are for Flowtron bug zappers. We do not know if they will work for other machines.
