Light bulbs burning out one after the other

[Jacques79]

3 weeks ago my rear brake light was burnt.

2 weeks ago my front lower right light went out.

This week apparently now my front left parking light is going.

Is this just too much of an odd coincidence for all my light bulbs to be going out at the same time?

When I replace a burnt bulb it seems another one somewhere else gets ''burnt'' a few days later and I get a warning message on my onboard computer near the tach.

Could it be faulty ignition switch or headlight switch?

Daytime running lights were installed by a Porsche dealer 6 months ago.

I have a 2006 Boxster S with about 45K miles.

Thanks
