are they h7 65w (high) & 55w low ?
change them to h7 55w, x2.
the 65w or some 75w upgrades are thinner and can blow easier on rough bumps and switch surge when changing.
55w not so easy.
and if you want then brighter, ya can get 55w ultra brite(blue lens but white light)
i' had the chinese cheap blue h7's in my bird for 2&half years after blowing 2 bulbs.

if you have a gel battery, that can cause spike damage too, and blow rectifiers etc, so acid battery in a bird.

something to try
