I did a quick, and somewhat better "fix". Sylvania has these "ultra" performance Silverstar bulbs. I bought a set of the 21w (matches factory watt) bulbs, and installed them this morning. The blinkers seem much brighter, and with the colour of the bulb thru the red, rear signal lenses...there is a super, slight amber tint. It could just be my imagination about the amber, but they are for sure brighter than the factory clear 21w bulbs. According to Sylvania their Silverstar bulbs are about 30% brighter and the about 10% wider and farther color throw. They were about $12, so really cheap. I like them!!
