I've got a 2005 DRZ400SM. It's got an aftermarket tail light / plate holder (I'm pretty sure it's aftermarket). The tail light was burnt out when I bought it. I replaced the bulb and it's burnt out already (about 3 weeks later). The brake light still works. It could be just coincidence and I just need to get another bulb but I want to check out if there's an electrical problem. My thoughts are the following: 1. Just a crappy bulb 2. The wiring is exposed and shorting out on the subframe somewhere 3. The bulb doesn't draw as much power as the original and it's getting overloaded. If it's 3, how will my signals affect it? I've got aftermarket signals that flash too fast. They're not LED but I guess there low wattage. Because I want to take my signals off anyway for dirt riding so I don't think bigger signals is the answer. Any thoughts?
