They work perfect without resistors
These lights are definitely the best turn signal lights you can purchase, very high quality, you can feel the quality just by touching them, and when you have them on you are always the brightest on the street, the yellow led are strong as the emergency vehicles lights. The white led provides an elegant and completes the look of your vehicle at night.

Brightest front turn signals to date.
What makes these much brighter is the white perimeter lights stay on when signalling with park or head lights on. This is different behaviour that's growing on me. The other nice thing is the perimeter light is not blinding but the hazards are. Nice and gets peoples attention when overtaking on inclement weather.

So far so good!
Installed these a few weeks ago and they are the only ones to work without a resister...and they work and look great. We will see how they work in the heat of summer but in the fall going into winter no overheating or issues!
