When it comes to automotive light bulbs, the naming conventions can get confusing. 5202, H16, and 2504 are commonly used as fog light bulb in vehicles.

This article will clarify the distinctions between these three common bulb types to help you purchase the correct replacement bulb for your vehicle.

5202 vs. H16

The 5202 and H16 bulbs are often confused with each other, but they are completely different. The H16 bulb has a traditional right-angled style connector base with a large rubber o-ring and three evenly spaced metal tabs to lock it in place. This makes it part of the H8/H9/H11 bulb family.

The confusion stems from some manufacturers incorrectly labeling the 5202 bulb as H16.

The 5202 has a tab-lock style base that is incompatible with vehicles requiring an H16 bulb.

However, in recent years, some manufacturers have made a new version of the H16 bulb that uses a T-shape design. This newer T-shape H16 is equivalent to bulb numbers 5202, 2504, PSX24W, PS24W, 5201, and 9009. It is not interchangeable with the original L-shape H16 bulbs but can be interchangeable with 5202 bulbs.

5202 vs. 2504

The 5202 and 2504 bulbs are both tab-lock style, but have slightly different tab alignments on the base. If you need to use a PSX24W bulb as a 5202 replacement or vice versa, you may be able to modify the tabs to make them fit.

This is not recommended though, as it can affect the bulb's performance. It's best to purchase the exact replacement bulb specified for your vehicle.

To summarize, H16 belongs to the H8/H9/H11 family, while 5202 has a tab-lock base. A new T-shape H16 version is compatible with 5202, 2504, PSX24W, PS24W, 5201, 9009, unlike the original L-shape. Comparatively, 5202 and 2504 have different tab alignments. Always use the bulb specified for your vehicle to ensure optimal performance.

About 5202 Bulb

The 5202 bulb, also known as PS24W, features a single filament and a PG20-3 base type. This bulb is designed for a stock power draw of 24W at 12 volts.

About H16 Bulb

The H16 bulb is different from the 5202 bulb. Notably, it has an L-shaped design and a PGJ19-3 base type. Like the 5202, it also utilizes a single filament.
