Those are blackline lights.. I know that the 2400 w/s heads use a different connector type than the 4800 w/s heads. The 2400 w/s heads fits all the 2401A/B/C, 2403 packs. I'm not sure if yours is the 4800 w/s head, but if it is, then you may need to buy 4800 w/s packs.. Give speedo a call or drive down to a dealer, they can let you plug it in their packs and to test the head to make sure its operational.
