Diode Dynamics, pursuant to the National Highway Traffic and Motor Vehicle Safety Act and Part 573 of the Code of Federal Regulations, has determined that SL1 LED replacement headlight bulbs sold by Diode Dynamics fail to conform with Federal Motor Vehicle Safety (FMVSS) Standard No. 108 “Lamps, Reflective Devices, and Associated Equipment.” The bulbs do not meet dimensional requirements for replaceable light sources, exceed limitations on luminous flux set forth in the standard and may cause increased or excessive glare for oncoming drivers. There are no known incidents related to the regulatory non-conformance.

As a remedy, Diode Dynamics is offering to replace the SL1 LED headlamp bulbs (Model Numbers DD0215P, DD0216P, DD0217P, DD0218P, DD0219P, DD0323P, and DD0340P) with halogen bulbs which comply with the requirements of FMVSS 108.

To obtain the replacement bulbs, please fill out the form below, IF YOU DO NOT HAVE AN ORIGINAL ORDER NUMBER, YOU MUST SUBMIT A RECEIPT OR OTHER PROOF OF PURCHASE WITH THIS RECALL FORM. To do so, you may either scan and upload the receipt or proof of purchase below, or you may print this page and mail it, along with a receipt or other proof of purchase, to: Diode Dynamics SL1 Recall, 3870 Millstone Parkway, St. Charles, MO 63301.

When the replacement bulbs are mailed to you, you will also be sent a prepaid label so that you may return the SL1 LED bulbs to Diode Dynamics in the same box in which the replacement bulbs are sent to you. We will then properly dispose of the bulbs.

We regret any inconvenience this may cause you.
