Are the modules at the rear of brake lights able to be tested? I have been constantly having trouble with the brake light faulty warning lights coming on. Having changed the rear globes to 21/5 watt types and removing a 21/5 and 32/4 watt globes (which were fitted). Still no joy. The modules : one has reed switch with diode and the other just the reed switch. Whats their function ? How can they be tested? Passenger side has the diode. (Aussie model) All contacts appear beautifully clean and don't appear to have been in any sort of bingle in the past...
