Most likely it's just the switch. It may be a burned switch connector; that's what happened on mine. I bought a replacement connector from Carquest.
The switches kept failing on me so I eventually just put a pair of relays in to power the lights directly.

if the switches are failing, there is a short somewhere creating extra load on the switch.
However, the setup is faulty anyways.
Switching to a relay setup is a good idea if you have the time.
You can buy a kit, or DIY.

Check out an article here on how to do it.
Which i'll also post when i get the money to do it myself.

I did not have any shorts, and had stock wattage bulbs but my switch burned up anyway. I replaced the connector and switch. The new switches would last a while and then start blinking.
I just put relays in and I haven't had problems since. The lights are a LOT brighter too.
