Vehicle Code 27007 does not appear on the DMV's list of one or two point vehicle code violations (http://www.dmv.ca.gov/dl/vioptct.htm). To be certain, you should contact an attorney to review your paperwork and advise you based on their review. Even if you cannot hire an attorney, you can always choose to fight the substantive evidence of the violation yourself. Most legal and county libraries have access to books on how to fight traffic tickets, and there is a great deal of information available on the internet as well.
Another cost effective angle would be to contact the DMVs "Mandatory Action Unit" they could give you a definitive answer. They are just difficult to reach.
