Additional Notes

The H11 is an ECE-standard single-filament halogen bulb rated at 12V and 55W, with a PGJ19-2 base, and holds ECE approval alongside US market approval.
The 9012 is an ANSI-standard single-filament enhanced halogen bulb rated at 12V and 55W, with a PX22d base, and is specified for the US and Canadian markets.
The 4114 is an ANSI-standard dual-filament bulb rated at 12V, designated for specialty applications in the US and Canadian markets.
Although the H11 and 9012 share the same voltage and wattage ratings, their base types differ, with the H11 using a PGJ19-2 base and the 9012 using a PX22d base, making the two bulbs physically non-interchangeable.
The GMC Sierra used the 4114 bulb for its daytime running lights across the 1999-2006 model years, representing the longest continuous bulb fitment in these specifications.
The H11 bulb was specified for the Sierra from 2007-2013, as well as for the 2014 Sierra 3500 HD.
The 2014 GMC Sierra carries two distinct daytime running light bulb specifications depending on trim: the 1500 uses the 9012, while the 3500 HD uses the H11.
The 9012 is described as an enhanced halogen type, a designation that distinguishes it from the standard halogen classification applied to the H11.
