I've recently noticed a problem with the "parking lights" on my 2004 Tigra. When I turn the ignition off and leave the indicator stalk in either the up or down position and then open the door, I get the warning buzzer telling me that I've done so. However I noticed the other day that the corresponding side and tail lights aren't lighting up when I get out of the car. I've checked the parking light fuses and they are ok and am wondering if anyone can shed any light on this? It's not something I use but am curious as to why the lights have stopped working but I am still getting the buzzer telling me that they are on? Any ideas? David
