Reinforced reinforced head light and a query

Heya. I’m in the habit of reinforcing ALL OF THE THINGS. Stumbled across a reinforced head light and turned it into a reinforced reinforced head light. Kinda goofy.
On a related note, does reinforcing car parts actually give any bonuses once installed? Will removing them revert them to their non-reinforced state? Haven’t had time to test this out.

Reinforcing the underlying part doesn’t make the part installed in the vehicle more sturdy.
