Faulty front indicators

[sourmanflint]

Hi all

I have just replaced my front bumper after a small crash, I took off the old one and installed the new one complete with indicators etc and all was ok for a while, but now about 50% of the time the front indicators do not flash, and I can hear a double time indicator click when driving. The wing mirror and rear indicators work as normal.

Am I right in thinking that I could just swap out the whole bumper and reconnect the wiring harness and that would be that, or is there something else I should have done? The new bumper was from a slightly different spec to mine (had factory fitted parking sensors) but wouldn't have thought that mattered. Stumped

I would fit 2 new good quality bulbs.

Check the bulb holders are clean & a good tight fit.

Check the wiring connectors also for any corrosion on the pins.

Thanks Phil

will try that. If I press down on indicator stem it sometimes stops but not always
