Papa Smurf: PM sent.

BMWX: Sure, you can. T5 Size Super white LED bulbs (SMD or HIGH POWER) can be used to replace the yellowish light bulbs. There are about 4-5 bulbs on each Angel Eye ring. So you will have to replace about 16-20 bulbs total, if you want to change the color of AE's to LED AE's. 20 T5 size bright white light bulbs cost around 10 bucks.

Local pick up is more than welcome.
