Hi there welcome and thank you for the question hope i can be of some assistance to your problem
Hi there I have a few question regarding your fault.
1, Is it both headlight bulbs that blow or just one side and is it blowing the fuse?
2, How long has this fault been happening for?
3, How long does it take between replacing the bulb and it happening again?
4, If you have your headlights on do they keep going bright and dim slightly and then bright again as thought they are flickering?
5, when the faults occur how do you get it to stop?
6,Do you have any problems starting?

Ok as you have said that your lights flicker and both your headlight bulbs are blowing then i would have the charge rate and the alternator of this vehicle checked as both these symptoms are a sign of over charging from the alternator too much voltage out put from the alternator causes great problems with the vehicles electrical systems you may have to have a garage check this system for you but let me know what they say.
