I put in a similar set up in my panel truck; but where yours are LED..mine are conventional bulbs.
You could use it as a turn signal … that's how mine are set up. My original parking lamps are just that… parking lamps.
Here's the dirty little secret on those, however….. You will need to spend a LOT of time modifying your headlamp bucket assemblies to accommodate these bulbs. Yes, they 7 inches in diameter at the front, but their shape at the back requires you to cut out a lot of material to get them to sit just right. I had some spare buckets so when I converted to these I had a back up plan.
The turn signal sections on mine are not real bright compared to the brightness of the headlamp and is hard to distinguish when it's on. They ARE very bright and draw a LOT of juice, so connect them using a relay kit or they will cut out on the thermal overload on the switch.
They do look cool once installed, tho.!
