Don’t be a “light cop”. It’s not very becoming.
he has a point though, I can't stand aftermarket plug in lights because people plug them in and don't index them so you don't get the proper light pattern and you blind people. for the fords there is a proper indexable one that you may have to put it in and out a couple time if you don't get lucky the first time, but it will have a proper cutoff and work good with the ford reflectors.
I am not sure if the sylvana's are indexable if they are they will be fine, if not they will be horrable.
