Indicator amber warning problem

Hi

Over the past year I have had my indicator light warning come on many times. I have changed the bulbs many time but it still come on randomly and ticks very fast. When I restart the car it goes off but it just comes on randomly again the garage could not find anything.

Does anyone know what may be the cause.

TIA

A Polo?
Where is the car from? Polo's and Pointers and GOL's (No not golf) I see are in Mexico.

As for the light. Have you or maybe a previous owner changed tail light bulbs or other bulbs etc to LED bulbs? Those will give that warning light.
