DO NOT use LED bulbs in place of your normal tail lamps.
They do not disperse light like a normal bulb and make it hard to see you.
And if you live where there is snow the tail lamp will not get hot and will be covered in snow and make you totally invisible to others.
I dont know where you live but around here it is a problem since all new cars come with LED tail lamps.
They are brighter than regular bulbs but still can be hard to see.
