Indicators - Flashing too fast

Hi guys

Just fitted some new micro indicators to my SRAD and theyre flashing too quick - as though there is a bulb out (but theyre all fine).

Ive heard of this problem before but dont know how to cure it. Ive seen some components which I assume you fit inline with the signals to load the circuit and slow the falsh rate back down to normal.

Thanks for any advice
