The headlight switch is bad on your '66. I have been through this on both my '63 & '66 at one point. The '66 I had the same problem. I was able to get an after market switch that was basically identical to the original thru Jeff Carter (come to think of it, it may have been a NOS) here in Seattle. He only charged me $3,000.00 for that part. Just kidding. It was $45.00 I believe. I should be good to go in that area for another 37 years. You may well be able to get the same part from a parts house for less, but if not check with Jeff Carter on his website at: www.jcauto.com or email him at: jcauto@xxxxxxxxxx If you are the old fashioned type like me you may write him at: 20815 52nd Ave W, Lynnwood, WA 98036 phone 425-672-8324, fax 425-771-2522. For both the '63 & '66 I got the switches from Jeff. Also, just for you '63 and older Imperial owners, Jeff is one of the only & most surely the best when it comes to rebuilding the Electroluminecent gauges in these cars. Also, he rebuilds clocks, either orig mechanical self winding, or places a quartz movement inside. On my '60 I insisted on the original mechanical, and it ran quite well, even if it did need adjustment occasionally, but the quarts he had already done on the '66 when I bought it. He also calibrates the gauges, and refinishes them to factory spec. He will also rebuild window, seat switches, etc...

Jeff does all Electroluminecent, including '66-'67 Chargers. He will not even deal with '67 or newer Imperials, '70 forward Challenger, Cuda's because, well, he just plain does not like them. That also applies to '71 and newer Chargers. -----Original Message----- From: mailing-list-owner@xxxxxxxxxxxxxxxx [mailto:mailing-list-owner@xxxxxxxxxxxxxxxx] On Behalf Of FltSgt@xxxxxxx Sent: Saturday, March 08, 2003 7:22 AM To: Mailing-List@xxxxxxxxxxxxxxxx Subject: IML: Parking Lights Yes, Head Lights No Hola While we are on "66 lights I now only have just parking lights. The head lights at one time would go on. Then I realized that three miles from the house they would go out of my life. Now I have no head lights. I can get away with dusk or dawn driving with the parking lights for a little bit, but it is getting old. On another note I took the left front wheel off to look at a leak from the wheel cylinder. Yelp it was bad so I bought pairs of wheel cylinders, A arm bushings, upper and lower joints, shocks, brake shoes and flex brake lines for the front. Rodger & Gabby
