LOW PROFILE HALOGEN HEADLAMP OPERATION
Comments have been received concerning headlamp operation. The models delineated above use the "F" TYPE lower profile halogen headlamps. These headlamps produce greater illumination output than previous halogen headlamp.
HIGH BEAM ILLUMINATION USES ONLY THE INNER HEADLAMPS. Low beam illumination uses only the outer headlamps. No attempt should be made to wire the low beam headlamps to operate on high beam, since illumination would exceed current legal limits .
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
