I bought my cooper with it's racing light and before I drove off the lot I notice the driverside racing light was shacking. The dealership said that was normal....

Does anyone else have a shcking driverside racing light? Anyone know how to fix it?

 

Do you mean your fog light is wobbling/loose? Or do you mean your rally light is wobbling/loose?

 

If its the RALLY Light (Ones on the hood) usually have a rattle/shack to 'em. Mine have a little more rattle than normal because of the dents in the back of the lights. lol Previous owner but nothing bad. They still look alright nothing you can tell from looking from the front. Oh Well. You can try adjusting the bolts that come thru the hood. But be careful not to mess up the grill.

 

Dreamweaver, if the light is loose on the mounting bracket, I think it was a 17mm spanner (wrench to Americans) to tighten the nut under the bracket. If the entire bracket is loose, you may have to drill out the rivets and re-install the bracket. A tip, if you are rivetting the bracket on, do the single rivet on the narrow end 1st.
