My GTS is almost 7 months old... At about 5 months, noticed one of my tailights (driver side) was blown... Replaced it and one month later its blown again...

Haven't been to the dealer, but was curious if anyone knows if the bulb keeps blowing out - is there a usual reason for this? Fuse, ballast, or something??

Thanks!

 

blown bulb replacement is covered under warranty for 2 years. Use it

You could have purchased cheap bulbs unknowingly, or there could have been many other factors to it burning out again.

 

You may have a short along the wire. Check to see if you can spot insulation missing or damaged.

You could check with a voltmeter how many amps they are drawing and compare it the fuse rating.
