Is it OK to take out the standard bulbs in the tail lights, and replace with the LED style replacements of the same size? Also, if this is OK, would anything special need to be done about the turn signal bulbs to replace them as well? Thanks.

 

It is a simple swap to switch the filament bulb to a LED style bulb, they are a little more costly and seem to lite up quicker than filament style ones. I installed my LED brake lights with bulbs I bought off eBay.
Turn signals use a resistor inline.
