i would get the blue, the only aesthetic difference between the two is the low beam magnifying glass is blue on the blue ones obviously and yellow on the yellows, clear on the clears. it just colors the light as it is being magnified. at night the blue looks cleaner because the clear is just like factory "clear" lights which are actually somewhat yellow. i had mine for so little time that i didnt get any pictures, but just search the internet and you will find thousands of pics of the projectors for all different cars
