One thing I found out is that my Back Off module no longer worked when I installed the LED taillight, the running light V lit up but the brake lights would not trigger. CD said that my Back Off module was not made for LEDs. CD does offer a similar module with some great flash patterns, its displayed right below the V rod taillights on their website.
Life is mostly froth and bubble;
Two things stand like stone:—
Kindness in another’s trouble,
Courage in our own.
Adam Lindsay Gordon. (1833–1870)
