Hello,

I bought a set of "visions super white" H4 bulbs for my car. I would like to install them. I was reading the manual, but it did not elaborate on how to remove the two arm fixtures that I must remove to get to the headlight assembly. The arms can be easily moved aside, I figured that part out. However, the plastic casing to which the arms connect to, I am unsure how to take them off, and haven't tried yet. Is there some sorta release, or I just use force and take them off? I'm a little timid to go ahead and experiment. Thank you if you can help.
