Hyundai Excel front side marker bulbs use 168 or 194 size configurations, while rear side marker bulbs require 194 size bulbs. The replacement chart covers 1986 to 1994 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Excel uses two bulb types across its side marker positions: the 168 and the 194. Both are ANSI-standardized miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage, making them physically interchangeable in terms of socket fit.
Although the 168 and 194 share the same T10 wedge base, they differ in wattage. The 168 draws 4.9 watts, while the 194 draws 3.78 watts. This difference means the two types are not electrically equivalent and are not intended to substitute for one another despite their physical similarity.
The front side marker position on the Hyundai Excel uses the 168 bulb for model years 1987-1994, representing the majority of the production run covered by these specifications.
The 1986 Excel is the only model year in which the front side marker uses the 194 bulb rather than the 168, placing it in a different fitment category from all subsequent years listed.
The rear side marker position uses the 194 bulb across all model years from 1986-1994 without variation, making it the only position with a fully consistent bulb specification throughout the entire range.
For the 1987-1994 Excel, the front and rear side marker positions require different bulb types, with the 168 at the front and the 194 at the rear. Installing either type in the wrong position would result in an incorrect wattage for that circuit.
The 1986 Excel is the only model year in which both the front and rear side marker positions share the same bulb type, the 194, across both locations.
