Tail light bulb keeps blowing out.

Ive been having a small problem with mybike lately. Its blown 3 tail light bulbs now in the past 2 weeks. Not that its expensive but its better to correct the problem than leave it and ride with no lights at night and crash.

I use double winding bulb and one of the winding which is the tail light keeps going. The brake light still works. I suspect that might be caused by the vibration but im not sure. Whatcha think?

The bike is a Gilera Cougar 125.

Does the tail light (and head light...) only come on when the engine is running?

Make sure all the bolts holding the fairings on are secure - i had a problem not long ago when the rear mud guard was a bit loose and vibrating causing my bulbs to blow.

also make sure you dont touch the glass part of the bulb as you leave a residue or something on the glass that can cause them to get too hot and blow out or something.

make sure the tail light bulb is the correct voltage & amperage for your bike. if the bulbs are the right ones then you have a short somewhere, check the connections inside the bulb holder & the wires going into the back of it. look for any exposed or worn insulation on the wiring where a live wire might be earthing.

Could also be an intermittent wiring fault. Check all of the associated wiring for sections that are rubbed through and grounding on the frame/other wires.

Just buy a LED bulb, stick it in and never ever look at it or think about it again. Razz

Halfords do them in packs of 2 iirc.
