Rear marker, brake, and turn signal bulbs should always be red
Use of white led bulbs in rear lights washes the red lens color to pink
Front marker and turn signal light bulbs can be white or amber
In order to not have to use resistors to prevent hyper-flashing, signal light LED bulbs should be at least 27W which is equivalent to 2.25A@12V and 1.88A@14.4V. Alternatively, if possible, replace the car's flasher with an LED flasher.
