I had this probelm on my 04 the floating head light reflector had to be ajusted down like a 1/2 inch at the dealer no more flashers the illumination was still the same you just arent squirrel hunting...

P.S. I went to the dealer and they told me the lights were properly ajusted.. I told them to reajust them down a little.. they did and no one flashes me any more these where the Halogen stock head lights.. Theres nothing wrong with your car just ajust the head light reflectors down a little....
