9005 and H11 are two of the most common headlight bulb sizes. If you are upgrading your halogen H11, H8 or H9 low beams to LED, you may have noticed a lot of kits that also include 9005. That is because many vehicles pair an H11 low beam with a 9005 high beam.
If your car uses that setup, it is worth upgrading the 9005 high beam at the same time, so both beams match in color and you only open the housings once. When you shop, you will see H11 kits, 9005 kits, and H11 + 9005 combos. This guide explains the difference and helps you choose.
What Is a 9005/H11 LED Combo Kit?
A 9005/H11 combo kit bundles the bulbs your front housing needs into a single package. The 9005 is the same bulb as the HB3, and the H11 shares its base family with the H8, H9 and H16, so a combo marketed for “9005/H11” often also fits vehicles that list H8, H9 or H16 for the low beam or fog position.
Most combos come in one of two layouts. A two-pair kit covers the high beam and low beam, four bulbs in total. A three-pair kit adds the fog lights, six bulbs in total.
Take the SEALIGHT G2 combo as a concrete example. It ships as three pairs (six bulbs) and pairs 9005/HB3 headlights with H11/H8/H16 low beam and fog bulbs
One point that matters before anything else: 9005 and H11 are not interchangeable. They use different bases and sit in different positions. A combo works only because it gives you one of each, not because either bulb can replace the other.
Combo vs. Separate Bulbs: The 5 Factors That Decide
Before you compare prices, run your vehicle through these five checks. They settle the question faster than any spec sheet.
1. Fitment: does your car really use 9005 and H11?
This is the make-or-break factor. Many popular vehicles do run a 9005 high beam and an H11 low beam, including several Toyota Camry and Highlander years, Honda CR-V and Pilot models, and a long list of Subaru and Nissan vehicles. But plenty of cars use a 9005 high beam with a 9006 low beam, or a single H4 bulb for both. If your low beam is not H11, a 9005/H11 combo will leave one position unfilled. Check what bulbs your car needs first.
2. Cost: one kit versus two or three pairs
A combo is usually cheaper than buying each pair on its own, because the kit price covers several pairs at once. The gap widens once you add separate fog bulbs. If you need high, low and fog anyway, the combo is almost always the lower total.
3. Color match across positions
Bulbs bought separately can differ in color temperature by brand and batch, so your low beam may look slightly cooler or warmer than your high beam. A single kit is built to one color target, so all front bulbs read the same. For drivers who care about a clean, even front end, that consistency is worth more than a few dollars saved.
4. Install effort
The install process is the same either way: open the housing, unplug the stock bulb, plug in the LED, and secure it. A combo does not make each bulb harder to fit. It does mean more bulbs in one session, but you only prepare the vehicle once and finish the whole front end in a single sitting.
5. Flexibility
Separate bulbs let you upgrade only what is actually dim, or try one series before committing to a full set. A combo is efficient but less flexible. If your fog lights are fine and only the low beam is weak, there is no reason to replace all six bulbs.
When a Combo Kit Is the Better Buy
Choose a combo kit if fitment confirms 9005 high beams and H11 low beams, and any of the following apply:
· Your stock bulbs are all original halogen and roughly the same age, so they are all due for replacement.
· You want the high beam, low beam and fog lights to match in color and brightness.
· You would rather place one order and keep one warranty than manage several purchases.
· You plan to keep the vehicle and want the full front lighting refreshed at once.
When Separate Bulbs Make More Sense
Go with individual bulbs when any of these applies:
· Only one position is dim or burnt out, and the rest still perform well.
· You looked but could not find a combo that matches your vehicle's exact bulb pairing.
· You want to test one series in your low beam before upgrading the rest.
· Your fog lights take a different base or a specific fog-focused design, and you prefer to choose that separately.
9005 vs. H11: Quick Fitment Check Before You Buy
You do not need a shop visit to confirm your bulb sizes. There are three reliable ways to check:
· Read your owner's manual. The bulb specification table lists the code for each position, including high beam, low beam and fog.
· Look at the base of the stock bulb. The code is usually stamped on the plastic or metal base.
· Use a bulb finder by year, make and model. This is the fastest option when the manual is not handy.
Here is how the two bulbs compare, so you know which position you are looking at:
| Spec | 9005 / HB3 | H11 / H8 / H9 / H16 |
| Common position | High beam (some low beam) | Low beam, fog light, DRL |
| Cross-reference | HB3 | H8, H9, H16 |
| Interchangeable with the other? | No | No |

Higher-output four-bulb set: SEALIGHT S7S 9005/H11
The SEALIGHT S7S 9005/H11 four-bulb combo includes two 9005/HB3 bulbs and two H11/H9/H8 bulbs. The specifications list 66,000LM and 260W per four-bulb set, 6500K, fan cooling with a heat pipe and copper board, IP68, and a 60,000-hour rating. It suits buyers who want the highest published output across both beams in one order. The higher lumen number is a manufacturer rating, not a guaranteed proportional gain in usable beam, so check the pattern in your own housing.
Shop the S7S 9005 + H11 kit.
Everyday four-bulb set: SEALIGHT S2 9005/H11
The SEALIGHT S2 9005/H11 combo pairs two 9005/HB3 bulbs with two H11/H9/H8 bulbs. It is rated at 14,000LM per four-bulb set, 240W per set, 6500K, fanless cooling, IP68, and a 60,000-hour lifespan, with a compact right-angle base. It is a sensible starting point when you want both compatible pairs in one box and prefer a fanless design that fits tighter housings. The compact base helps, but space behind the housing still varies by vehicle, so check clearance before install.
Shop the S2 9005 + H11 kit.
Complete six-bulb option: SEALIGHT G2 9005/H11/H11
The SEALIGHT G2 headlight-and-fog-light combo includes two 9005 high-beam bulbs, two H11-compatible low-beam bulbs and two H11-compatible fog-light bulbs: six bulbs across three pairs. The specifications list 26,000LM per complete set (20,000LM headlights plus 6,000LM fog lights), 90W per set (70W headlights plus 20W fog lights), 6500K, IP68, and a 60,000-hour rating.
This is a practical option when all three positions need attention and all three pairs fit the vehicle. If your car uses H10/9145/9140 fog lights instead, look at the G2 9005/H11/H10 six-bulb setup rather than trying to fit H11 fog bulbs into an incompatible socket.

FAQs About 9005/H11 LED Combos
1. Do I need both high beam and low beam bulbs?
For most drivers, yes. If your low beam is due for replacement, the high beam is usually the same age and on the same schedule, so upgrading both at once keeps the color matched and saves a second install. If the high beam is clearly still strong, you can start with the low beam pair and add the 9005 later.
2. Is a combo cheaper than buying bulbs separately?
Usually yes. A 9005/H11 combo covers multiple pairs in one price, so the per-pair cost tends to be lower than buying each pair on its own, especially once you add fog bulbs.
3. Can I swap a 9005 for an H11, or the other way around?
No. The two bulbs use different bases and fit different positions. A 9005/H11 combo works by giving you one of each, not by making them interchangeable.
4. Which bulb is the fog light in a 9005/H11 combo?
It depends on your vehicle. Many cars use the H11 (or H8/H16) for fog lights, which is why combos pair the H11 with fog bulbs. Some trucks use a separate fog base such as H10 or 9145, so confirm the fog bulb size before you buy.
5. Can I buy just one pair instead of the full combo?
Yes. If only one position needs new bulbs, buy that single pair. The size pages let you pick just H11 or just 9005.
6. Will an LED combo cause dashboard error codes?
Some vehicles show a bulb-out warning or flicker after an LED swap. A CANBUS-ready kit or a decoder harness usually solves it. Check whether your vehicle is known for this before ordering.
Final Words
The combo versus separate decision comes down to fitment first, then how much of the front end you are replacing. If your car runs a 9005 high beam and an H11 low beam and the stock bulbs are all aging, a combo gives you matched color, one order and a lower total price. If only one position is weak, buy that single pair and skip the rest.
