Additional Notes

The 168 bulb is the most frequently specified license plate bulb across the Hyundai Tiburon's production run, appearing in the 1997-2004 and 2007-2008 model years.
The 168 is a T10 miniature wedge bulb rated at 12 volts and 4.9 watts, conforming to ANSI standards for the US and Canadian markets.
The T10 wedge form factor uses a plastic wedge base with no separate metal contacts, as the filament leads themselves make direct contact with the socket.
The DE3423 festoon bulb is specified for the 2005-2006 Hyundai Tiburon, representing a departure from the wedge-type fitment used in surrounding model years.
The DE3423 is a 41mm festoon bulb operating at 12 volts, using end-cap contacts at each end of the cylindrical housing rather than a wedge or bayonet base.
Festoon and wedge bulbs are mechanically incompatible with each other, as they require different socket types and cannot be substituted without a socket adapter or wiring modification.
Both the 168 and DE3423 carry ANSI standardization for the US and Canadian markets, meaning their physical and electrical characteristics conform to a defined specification rather than being proprietary to a single manufacturer.
The wattage of the 168 at 4.9 watts places it in the low-power range typical of license plate illumination, where heat output and current draw are minimal concerns under normal operation.
