The spring clip is pretty weak, I remember having to bend mine to increase the tension so the bulb doesn't wiggle around so much. My next project is to install the round LED headlight I bought a few months ago. I came with some fork brackets that don't really fit, but I pretty much figured out how to make some brackets that utilize the existing brackets for the headlight housing.
There is thread about replacing the running light with an LED.
