Just thought I would mention that Bekkers carries bulbs that are silver/blue-ish in color, but when engaged, are bright amber. They cost $9.00 (USD) each. Shipping will be about $6.00 for both. I have not ordered these bulbs yet, but I defiantly will. I hate the amber look, but I've been pulled over twice with the bright PIAA Extreme white bulbs, so I have the amber ones in there now. I think you can find the bulbs at their website, www.Bekkers.com
or call them at 1-800-624-5410 (I saw them in the latest catalog).
