5202 (H16-EU) & 2504 (PSX24W) LED Fog Light Bulbs
Upgrading your vehicle to 5202 LED Bulbs or 2504 LED Bulbs significantly increases the light output of your vehicle's lights. 5202 bulbs and 2504 bulbs serve as the fog lights in newer vehicles such as the 2014-2018 GMC Sierra, 2018+ Jeep JL Wrangler, and the 2013-2017 Subaru BRZ, among many others.
Diode Dynamics is proud to offer several plug-and-play replacement bulbs in the 5202 (H16-US) and PSX24W size, including our SL2 Fog Light LED Bulb!
There is a great deal of confusion when it comes to the differences between 5202, H16, and PSX24W bulb sizes. The main source of confusion is the fact that "H16" is used for two types of bulbs: in Japan, it is an H11-style bulb, with standard H11-size base, running at a lower power level. However, in Europe, "H16" was used to refer to the newer tab-lock style of bulb.
To prevent confusion, we are now referring to the tab-lock style as its US trade number "5202," rather than H16. Similarly, the US trade number for PSX24W base is 2504.
So what is the difference between 5202 (H16-EU) and 2504 (PSX24W) LED bulb sizes? They are both tab-lock style bulbs, but they have differences in the alignment tabs on the base.
