GMC Jimmy headlights are an integral part of safe driving. Because the headlights are positioned above the bumper, they must be adjusted properly to avoid blinding other drivers. Modern GMC Jimmys are equipped with daytime running lights as well.

Standard equipment is a composite design which includes the low beam, high beam, and blinker. Some modern designs of the GMC Jimmy include a fog light.

While the bulbs can be replaced independently, damage to the lamp means that the entire unit must be replaced, which can be expensive. Cracked headlight housings can remain functional, but are unlikely to pass most state inspections. Damaged housings should be replaced, as water can enter into the system and cause a short or other damage. To avoid expensive repair bills, consider investing in protective headlight covers for your truck. While the best thing the average driver can do to keep GMC Jimmy headlights working well is to keep them clean and replace burnt out bulbs, there are upgrades available to the standard halogen design which can drastically improve nighttime visibility. The most expensive and effective route to go is to upgrade to a xenon system, which can give you great illumination at night, while lightening your wallet up to a thousand dollars. The bluish light of xenon is prized among tuners, but not everyone can afford it. There are high-intensity discharge systems available, also at a rather high cost. The more affordable route can be to upgrade the bulbs. Some have been known to purchase bluish tinged bulbs to give the appearance of xenon and a fraction of a cost. There is no evidence to suggest that blue bulbs alone will improve nighttime visibility, and may actually decrease contrast.The most sensible and affordable upgrade to GMC Jimmy headlights is most likely upgraded bulbs, which can burn brighter and cast greater light.
