It seems the Ohio link in the first post is broken. Here's what seems to be the new link. They don't have all the sections of the FAQ finished though.

FAQ - Equipment
What are the guidelines for using windshield wipers according to the new regulation?
Effective Jan. 1, 2010 - Under Ohio Revised Code 4513.03, all vehicles upon a street or highway must have headlights on while using windshield wipers. This is a secondary traffic offense, which means vehicles cannot be stopped solely for a violation of this statute. A citation for this offense is a minor misdemeanor. Fines will vary by court district.
What percent can windows be tinted on the vehicle?
According to Ohio Administrative Code 4501-41-03, on Ohio registered vehicles window tint must allow 50 percent light transmittance on the rear and side windows, and 70 percent transmittance on the windshield. In other words, the tint can not be darker than 50 percent on the side and back, and 30 percent on the windshield.
Light transmittance of 50 percent does not apply on the windows behind the driver if there are outside left and right side mirrors. Remember, auto glass is slightly tinted from the factory and will make the tint you apply to your windows darker than advertised by the tint manufacturer.
What is the maximum lift height? And how do you measure it?
Specifications for bumper heights are covered in section 4501-43-04 of the Ohio Administrative Code. Maximum bumper heights shall be determined by the weight category of Gross Vehicle Weight Rating (GVWR). The height is measured from the ground to the bottom of the bumper or frame rail

What colors and types (under body, in-car, etc.) of neon lights are legal?
Lights must not rotate, oscillate, or flash, but state law does not prohibit the use of colored neon lights under your car as long as they do not interfere or blind other drivers.
Ohio Revised Code, section 4513.17 prohibits flashing lights on motor vehicles with the exception of emergency vehicles, turn signals, and hazard flashers.
As long as the neon lights are less than 300 candle power they are not in violation of any State law. If the lights are more than 300 candle power they must be directed to strike the pavement the vehicle sets upon at a distance of no more than 75 feet. The lights can not exceed 500 candle power.
State law requires a white light to illuminate the rear license plate.
What is involved in a motor vehicle inspection?
A motor vehicle inspection is a very brief check. The inspector checks to assure all lights, signals, and safety equipment is installed and in working order. Some of these items include: Turn signals, stop lights, head lights, horn, safety belts, emergency brake, and mirrors. In addition, equipment violations such as missing bumpers, cracked windshields, and poor tires will result in failing an inspection.
