For the 2018 Lexus LC 500, fitment can differ by trim, lighting package, body style, and region, so always confirm the exact lamp location before buying.

FAQ
Does the 2018 Lexus LC 500 use LED lighting in most positions?
Yes. The bulb chart for the 2018 Lexus LC 500 shows LED lighting for many exterior and interior positions, including the headlights, fog lights, brake lights, turn signals, license plate lights, dome light, map light, and cargo-area lighting.
How do I use this page to find the right bulb for my LC 500?
Start by matching the light location on your car to the same position listed on the page, such as front turn signal, rear turn signal, or glove box light. This helps you verify the correct bulb size or assembly by function instead of guessing from the vehicle model alone.
Are the headlight high beam and low beam bulbs replaceable on the 2018 LC 500?
The chart lists the headlight high beam and low beam as LED on this model. Because of that, the lighting may be part of an LED assembly rather than a simple replaceable bulb, so check the exact headlamp configuration before purchasing parts.
Do fog lights on the 2018 Lexus LC 500 use LED bulbs?
Yes, the front fog light position is listed as LED. If your car has a different setup due to market or trim differences, confirm the installed lamp before ordering.
What about the brake lights and center high mount stop light?
Both the brake light and the center high mount stop light are listed as LED on the 2018 Lexus LC 500. If one of these stops working, the repair may involve an LED module or complete lamp assembly rather than a standard bulb swap.
Are the front and rear turn signals the same bulb type?
The page lists both front and rear turn signal light positions as LED. Even when both are LED, the physical lamp design and service method can still differ between the front and rear locations.
Does the license plate light use a standard bulb?
No, the license plate light is listed as LED for the 2018 Lexus LC 500. That means you should verify whether the vehicle uses a serviceable LED bulb, a module, or an integrated lamp housing.
What interior lights are covered for this year and model?
The chart includes the glove box light, trunk or cargo area light, dome light, map light, and interior door light, all listed as LED. These positions are useful when you need to confirm cabin lighting fitment one location at a time.
Are the side marker lights and parking lights LED too?
Yes. The front side marker light, rear side marker light, and parking light are all listed as LED on the 2018 Lexus LC 500. As with other LED positions, the exact service part may vary by trim and market.
Could trim or market differences change the bulb fitment on my LC 500?
Yes. Trim level, lighting package, body style, and market can all affect the exact lamp design and replacement method. That is why it is best to verify the specific lighting position on the car before ordering.
What should I check before buying a replacement bulb or assembly?
Check the installed bulb or lamp housing, confirm the exact light position, and compare it with the vehicle’s original equipment. This is especially important if the car has been converted to aftermarket LED bulbs or if a previous owner replaced a factory part with a different style.
If my 2018 Lexus LC 500 has LED lights, can I still upgrade them?
Some owners choose aftermarket LED upgrades, but fitment depends on the original lamp design and connector type. For LED-equipped positions, the better approach is often to match the original assembly rather than assume a universal bulb will fit.
