I read on another website somewhere that instead of buying smoked indicators, you could use black RIT clothing dye. Boil a pot of water, add the dye & indicators and simmer for between 10 & 20 minutes depending on how dark you wanted them. Then rinse them in warm water & let them dry.I done them for 20 minutes & it didn't work. They are still almost as orange as they were before.
And another thing to take note of:
On the rear indicators the 2 screws closest to the number plate are actually bolts which hold the indicator onto the indicator stem. All the rest of the fasteners where screws.
