To all MCI Distributors

There may be a problem with the locking of the lens ring on the Model MCI 50 XP Headlight fixture. If you have any customer with headlight housing stamped on the back at the bottom of the housing between the gland opening marked with ( R18 ). The locking set screw may not lock the lens ring of these units. A locking tab and cap screw was supplied for locking in the original assemblies.

            Please let your customers know and MCI will supply the locking hardware at no charge.

Sincerely,

Larry W. Rowley
