Was on mod-express and saw an option for a relay kit?

Do I need one? Car is a 92 Lude...

 

You don't necessarily need the relay kit, but it is a good idea. The relay kit draws power directly from your battery, thus it won't wear out and melt your stock lighting harness. It's definitely worth it for the $10 they charge. Last week I purchased a 6K Kit for my 02 civic with the relay and it was really easy to put together.
