We get used to niggling faults with these cars. After all they are hand-built. Occasionally I run a full check of the lights as there are some you cannot see while driving (brake lights, indicators, flashers). Normally a bulb failure in the indicator system is obvious as it starts flashing at twice the speed. But I have so much on the system (6 flashing bulbs, 3 different lights in the cockpit and an industrial strength buzzer) that the loss of just one bulb has no effect.
On this occasion I saw the nearside front indicator was not operating. To narrow down the cause I swapped the bulbs over and it was still the nearside one that wasn't working so it was obviously not getting power.
I also tested the emergency flashers to make sure it was just the bulb (remember I have an independent emergency system with it's on flasher relay. Unfortunately they didn't work at all. Luckily the design of my dashboard means I can reach behind the switch, so I wiggled all the wires and they suddenly started working so it was a dodgy connection.
Back to the normal indicators. For various reasons I have 3 bullet connectors between the bulb and the wiring loom so that was my first port of call. They all looked solid, but just tbe sure I took each one apart, cleaned the connectors and put them back. After this I tried again and everything worked perfectly. Just normal corrosion over time I guess.
