Been thinking about this one for a while, don't know how viable it is,
getting the pop up headlight mechanism from a MX-5 or MR2 and adapting it to fit an FTO,
I presume you could use the existing plastic lenses as the caps, and that space is more limited around the FTO's headlight area than on the MR or MX.
You'd probably have to make up your own light unit, and have the lights only pop up a small bit.
could look cool?
