What is the best place to purchase a head light ballast for a 2001 CL?My pass.side head light does always work,I'm trying the bulb first,if that doesn't work then the ballast.They relly are expensive..!!!!!

Try http://theretrofitsource.com

I got a set from retrofitsource as well. Be aware that you will need to splice into the wires for the power as the plug type does not match.

Switch your bulbs over first to see if its the ballast or not. The bulb is about $110.00 from parts store and ballast is twice as much.

Got lucky....just a blown bulb..
