Overview
The Acura Integra has used replaceable headlight bulbs since its launch for the 1986 model year and again with the 2023 relaunch. These small lamps let you switch between low-beam and high-beam light so you can see and be seen at night or in bad weather. Different generations take different bulb sizes-knowing the right size keeps you from forcing the wrong plug or melting a socket. Keeping the bulb in good shape is more than comfort; U.S. safety rules under FMVSS 108 require working headlamps on every road-going car. (Wikipedia, eCFR)
Fitment Guide
| Integra Generation | Low-Beam | High-Beam | Notes |
| 1990-1993 (2nd gen) | 9006/HB4 | 9005/HB3 | Common halogen twin-bulb set-up (NTXGlow) |
| 1994-2001 (3rd gen) | 9006/HB4 | 9005/HB3 | |
| 2023-present (5th gen liftback) | Factory LED modules* | 9005 adapter for aftermarket | Uses built-in LED; some owners add 9005 for auxiliary high beam (SEALIGHT, Acura OEM Parts Online) |

*Factory LED assemblies are not serviceable at the bulb level; the whole module is replaced if the LED fails.
Symptoms of Failure
A dying headlamp bulb often dims, flickers, or changes color toward yellow or pink before it goes out. You might also hear a chime because many Integras share the warning tone for lights and seatbelts. (Chapel Hill Tire)
Replacement Tips
Upgrades & Options
Legal & Safety
The U.S. Code of Federal Regulations §571.108 sets the minimum brightness and beam pattern every replacement bulb must meet. Lamps must also carry a "DOT" mark proving compliance. (eCFR, Legal Information Institute)
Driving with one lamp out is illegal in every state; fines range from about $10 to over $200 plus court fees, and in places like California the base ticket is $238. (Sulte Law Firm)
In the UK, a faulty headlamp carries a £100 on-the-spot fine and three licence points under the Road Vehicles Lighting Regulations 1989. (The Sun)
Maintenance
Typical halogen bulbs last two to five years-or roughly 900-1,000 hours-so inspecting them at each oil change catches problems early. (Reddit)
Keep the headlamp lens clean; a hazy lens can cut light by 40 % even with a new bulb. Plastic-safe polish kits restore clarity.
Environmental Impact
LEDs use only about a quarter of the energy older halogens use for the same light, which means less load on the alternator and lower CO? emissions over time. (LiteLab, HitLights)
Because LEDs last tens of thousands of hours, they cut waste in landfills and reduce the number of glass and metal capsules thrown away.
Frequently Asked Questions
Q: What headlight bulb does a 1996 Acura Integra use?
A: The low-beam is 9006 (HB4) and the high-beam is 9005 (HB3). (AUXITO)
Q: Can I put LED bulbs in my stock Integra housing?
A: Yes, many plug-and-play LED kits fit the same 9005/9006 sockets, but choose ones that keep the beam pattern so you do not blind other drivers. (Autolist)
Q: How do I know my bulb is about to fail?
A: Look for dim, flickering, or color-shifting light. If one side is darker than the other, change both because they age together. (Chapel Hill Tire)
Q: Are LED bulbs legal?
A: They are legal if the packaging says "DOT" or "SAE" and they meet FMVSS 108 beam specs. (eCFR)
Q: What is the fine for a burnt-out headlight?
A: In many U.S. states it starts around $25, but places such as California list $238 before fees. (Sulte Law Firm)
Q: How often should I change halogen bulbs?
A: Plan on every few years or after 1,000 hours of use to avoid sudden failure. (Reddit)
Q: Do brighter bulbs overheat wiring?
A: Standard-wattage LEDs draw no more power than stock halogens, so wiring stays cool. (NAOEVO)
Q: What color light is best?
A: Around 5,500 K gives crisp white light without the blue tint that causes glare. (Vox)
Q: Will a headlight restore kit help?
A: Yes-polishing a cloudy lens can recover 30-40 % lost output for very little cost.
Q: Can I drive to the store with one headlamp out?
A: You might get only a "fix-it" notice, but an officer can still write a citation on the spot. Safer to replace the bulb first. (Reddit)
