2018 Jeep Wrangler Headlight Bulb Size
The 2018 Jeep Wrangler JL rewrote the rules for what a Wrangler could be — a turbocharged 2.0L engine option, eTorque mild-hybrid technology, massively improved on-road refinement, and a completely redesigned headlight system that broke from decades of tradition. The 2018 Jeep Wrangler headlight bulb size is H11 for the low beams and 9005 for the high beams, a major departure from the JK generation's single H13 dual-beam bulb. The fog lights use a PSX24W bulb. Higher trims like the Sahara and Rubicon received factory LED headlights, but the Sport trim shipped with halogen bulbs in the new housing design.
If your 2018 Wrangler JL came with halogen headlights, upgrading to 2018 Jeep Wrangler LED headlights brings the Sport trim up to the same lighting performance as the factory LED-equipped Sahara and Rubicon — often exceeding it, since aftermarket LED kits typically produce higher lumen output than the OEM LED modules.
Best LED and HID Kits for the All-New 2018 Wrangler JL
The 2018 JL's switch to separate H11 low beam and 9005 high beam bulbs means you can upgrade each beam independently, choosing the kit that best suits each function. For the H11 low beams — your primary nighttime driving light — an LED kit delivers a wide, controlled beam with a sharp cutoff that keeps light out of oncoming drivers' eyes while flooding the road ahead. The 9005 high beam conversion adds long-range reach for open stretches of highway and dark trails where you need maximum distance.
HID kits are available for both the H11 and 9005 positions and deliver the highest possible light density per bulb. For JL owners who regularly drive long distances on unlit roads, the depth of an HID beam at highway speed is difficult to match. Each position requires its own ballast, so a full low-and-high HID conversion involves two ballasts per side, mounted in the spacious JL engine bay.
Do not forget the PSX24W fog lights — LED fog light replacements for the JL complete the front lighting overhaul and ensure uniform color across all three lighting positions. HID Nation ships every kit free with a lifetime warranty, covering both beams and fog lights for the life of your ownership.
Frequently Asked Questions
What headlight bulb size does the 2018 Jeep Wrangler use?
The 2018 Jeep Wrangler JL uses H11 bulbs for the low beams and 9005 bulbs for the high beams. The fog lights use PSX24W bulbs. This is a completely different setup from the previous-generation JK Wrangler, which used a single H13 dual-beam bulb. The 2018 JL requires separate bulbs for each beam function, so you will need both an H11 kit and a 9005 kit for a complete headlight upgrade.
Does the 2018 Wrangler JL have the same headlights as the JK?
No. The 2018 JL represents a complete redesign of the Wrangler headlight system. The JK used round headlight housings with a single H13 dual-beam halogen. The JL uses newly shaped housings with separate H11 low beam and 9005 high beam sockets, plus PSX24W fog lights instead of the JK's H16. No headlight components are interchangeable between the two generations. This is the most significant headlight change in Wrangler history.
Should I upgrade only the low beams or both beams on my 2018 Wrangler?
Upgrading both the H11 low beams and 9005 high beams is recommended for the best results. The low beams handle the majority of your nighttime driving, so they deliver the most noticeable improvement. However, leaving the high beams as halogen creates a jarring color mismatch when you toggle between beams — crisp white on low, yellowish on high. Upgrading both positions gives you consistent 6000K output across the entire beam range and ensures your high beams match the improved performance of the low beams.
Do 2018 Wrangler JL LED headlights need a CANBUS decoder?
The 2018 JL is generally more compatible with aftermarket LED bulbs than the older JK generation. Most quality H11 and 9005 LED kits install without triggering flicker or error codes on the JL platform. However, some budget LED kits may still cause issues on specific JL configurations. If you experience any flickering after installation, an inline CANBUS decoder for the affected position resolves it immediately. HID Nation's JL-compatible kits are designed to work without additional decoders on the 2018 Wrangler.
What fog light bulb does the 2018 Jeep Wrangler JL use?
The 2018 Wrangler JL uses PSX24W fog light bulbs, which is different from the H16 used in the previous JK generation. LED replacements for the PSX24W socket are available and install the same way as the factory bulb. Upgrading the fog lights alongside the H11 and 9005 headlights ensures all forward lighting shares the same white color temperature, giving the JL a cohesive, premium look that matches or exceeds the factory LED setup on higher trims.
