If you replaced the bulbs on his car with LEDs, it is inevitably faced with the problem that automatically doubles the blink rate. The LEDs are namely much less load than a light bulb. So keep the electronic "Oh! because a bulb is broken, "and shows the driver of this defect by the blink rate. If you want to go then that is not with LEDs and a hyperactive indicators over the place, so what you have to change, especially as prescribed by law and that the flashing rate 1.5 Hz ± 0.5 Hz (= 90 light phenomena per minute ± 30) must be.

In fact all the cars turn signal relay function identically. One finds in it a small capacitor, the discharge rate controls the flash rate. Doubling the capacity of the capacitors, approximately halved the blink rate. Here the example of my turn signal relay from the Golf IV / Bora (which is integrated into the hazard light switch). Here you will find a 4.7 uF capacitor, so you can solder an additional capacitor in parallel with 4.7 uF or replace the existing 10 uF capacitor for one with a. I prefer to solder one hand, because the whole is rapidly reversible, and then one comes already very ill at the component side of PCB. Please observe the correct polarity, otherwise it may burst and then Elko stinks of fish .
