The front turn signals on most 1999 Camrys use a 7440 or 7443 bulb, while the rear turn signals typically use a 3156 or 3157 bulb. Exact sizes can vary by market and trim, so it’s best to confirm by checking the bulb in your car or consulting the manual.
Front turn signal bulb sizes
Before replacing the front indicators, identify which bulb size your specific Camry requires. The front housing commonly accommodates one of two similar bulb numbers, depending on the assembly.
- 7440
- 7443
In practice, most 1999 Camry front turn signals use one of these two sizes. If you’re unsure, bring the old bulb to the parts counter or compare the base on the removed bulb with a reputable bulb guide to determine which size you need.
Rear turn signal bulb sizes
Rear indicators often use a slightly different set of bulb numbers, reflecting dual- versus single-filament designs in taillight assemblies.
- 3156
- 3157
Choose between 3156 or 3157 based on whether your rear turn signal is a single-filament or dual-filament design. If the rear signal also serves as a brake light, you may need the dual-filament version (3157).
How to verify the exact bulb for your Camry
To ensure you buy the correct bulb, perform these checks. First, remove the lens and the bulb from the socket to read the part number stamped on the bulb itself. Second, compare the base configuration (single vs. dual filament) with known references or your owner’s manual. Third, note the color of the lens (amber for most turn signals) and match it with the bulb’s appearance. Finally, if you’re unsure, bring the old bulb to an auto parts store or consult a local Toyota dealer for the precise fitment for your VIN, as regional variations can occur.
Summary
For a 1999 Toyota Camry, front turn signals commonly require 7440 or 7443 bulbs, while rear turn signals commonly require 3156 or 3157 bulbs. Always verify by inspecting the existing bulb, consulting the owner's manual, or cross-checking with a parts professional to accommodate variations by market or trim.
Additional notes
If you are replacing both front and rear bulbs at once, consider purchasing a small mix of 7440/7443 and 3156/3157 ahead of time to ensure you have the correct sizes on hand. Proper installation also requires ensuring the bulb is seated correctly and the socket is clean to prevent poor contact or premature burnouts.
