In Massachusetts driving with an expired inspection sticker can result in a $50 fine and an insurance surcharge according to the information we were able to find.

The schedule of points and surchargeable items is found inside 211 CMR 134 (Code Of Massachusetts Regulations) and you should also be able to get information on what minor and major traffic offenses will result in a surcharge for your auto insurance.

The Registry of Motor Vehicles (RMV) site notes that neon (fluorescent) lights are illegal and are not approved for use in Massachusetts. And in general most states do not permit blue lights to be used on private personal vehicles and only on designated law enforcement or state vehicle, so that a person cannot impersonate a police officer by using blue lights.

As for the headlights, without knowing the exact citation your son received for them we cannot say if they are legal or would have a surcharge placed against your insurance for this offense. It would appear that they work up to the standards that the inspection process checks for but the type of headlight may be illegal, which the inspection center may not necessarily check as part of their checklist. 

You can check with the RMV or the police to see if your son's citations for the blue lights and headlamps were written up correctly and how to look up the laws pertaining to these items. I did not see these equipment issues as a surchargeable item but check with the MA Insurance Regulator to find out for certain.
