Hello, 

One of the most common issues that leads to premature failure of your vehicle's various bulbs is excess voltage running through your system. While several problems can be attributed to these symptoms, your most likely looking at an issue with your battery or your alternator. 

You will need to have the voltage going to the bulbs tested to verify that they are in fact getting too much power. Secondly, you will have to determine if this is normal for the vehicle and you need to upgrade your bulbs, or if this is abnormal and you need to make changes to the vehicle's charging system.
