My @ indicators were playing up - noticed this last year before pulling it to bits.

Upon further investigation, the connection wires are all ok - took the indicator relay off and pulled it to bits to see what was going on - rusty as a very rusty thing inside - hence they wouldnt flash - just stay on.

Popped into our good friends at H, and picked up a new 2 pin indicator relay for £4.99 - its cheaply made and needs a dab of silicone around the base to keep any future water out, and a zip tie to fix it in place, but for £4.99 i aint complaining - it works

Cheapest id seen specific to the RD04 was £14.99 plus post
