I would like to know what’s means about led car lights vs regular.

I think your mentioned regular means car halogen lights.

Car led lights and regular are good in different positions.

If you have spare cash, I think car led lights are better than regular.

Comparing with regular, car led lights are much smaller size.

So car led lights can be designed all kinds of special and beautiful models.

In order to make you clearly our led car lights vs regular, I will show you pictures as below.
