1969 Race Dart w/ 426 Hemi- garaged for 45+ years
I put the plug / play LED headlights and reverse light bulbs in my Duster and HemiMarks Demon. Easy / peasy....and WOW! are they bright. They plug right in to your OEM harness with zero effect on charging system. They have a relay built into the new harness that tucks easily behind the headlight bucket.
Put 60 miles (one way) on the Duster last Friday driving to Norwalk / Summit Raceway for a free day (9am-3pm) of fun drags courtesy of Summit / Atech.....no discharge effect what so ever.
Demon has the new LEDs and they look almost OEM.
