I put LED bulbs in my front turn lights and side marker lights. I already have LED tail lights. They are substantially brighter. I like mods/upgrades that improve the safety or mechanics of my jeep.
About LED's, the mfg. recommended that if you put an LED into a light that has a red lens, use a red bulb, a yellow lens use a yellow bulb. Unless its cosmetic like a dome light. Then you can use red, blue or yellow. Whatever you want.
I can't take pictures because its very hard to photograph the difference. But a before and after test in a darkened garage was markedly different.
Next project is new axle joints. Hopefully this week.
