It features an extensive lighting system powered by a dual-bulb halogen configuration using separate 9006 low beam and 9005 high beam bulbs for precise light distribution.

Can You Put LED Bulbs in a 1999 Pontiac Bonneville?
Upgrading to LED is one of the most effective ways to modernize your Pontiac's appearance and safety profile. We recommend starting your upgrade with the 9006 low beams, as they see the most use. Adding a matching 9005 LED kit later will complete the look and ensure consistent lighting performance. Don't forget the 880 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
