I plan to add these at some point down the road

right now i put in crakedbacks relay kit and i did notice the lights are already brighter when turned on while sitting in the shop.
At the moment i have those sylvania lights but i do have some Ge 6024 nighthawks on their way. Everything i have read about bulbs the nighthawks are the way to go unless you want to go all out and buy some cibies that are near impossible to find.
Most people will link you to daniel stern (slantsixdan) on the interwebs, but he seems shady to me.
The Hella lights posted up is suppose to be the second best thing out there for lights and then the nighthawks as the third best option (budget minded)
Everything i have read is add the relay kit and it will be the best starting point. The lights get their power directly from the alternator/starter/battery and feed the full 12 volts to the lights.
The relay package can be pieced together from some junkyard cars, but i didnt have any time to piece together my own setup so i just went with crackedbacks kit.
