Hey Sheridan, I've seen similar issues on other vehicles wherby one of the bulbs is actually gone which triggers the double flash rate... I assume you've checked that?
In the meantime I'm moving this to general tech help where it should#ve been posted....You're far more likely to get help there than in the forum help section.

I'm sure Thermo or one of the techs will be able to give you the definitive answer soon

Good luck

Mine did this on my 99 xk8 coupe forever. But after several bulbs the dealer said that they have had problems with grounding. They installed a secondary ground on both tailight assemblies. All it amounted to was adding a 16 ga wire with a closed loop on both ends. The wire is about 8" long and one end is on the metal of the tail light assembly the other end was attached to screw stud near the assembly. I have been troulbe free for about 5+ years.
