Used for: Turn Signal Light Bulb Rear
This page covers the 2021 Genesis G70 and helps you verify the correct bulb size by lighting position. Instead of guessing from a single “one-size-fits-all” list, you can check the exterior and interior lamp location you need and match it to the bulb chart for this year.
The 2021 G70 uses LED lighting for many exterior and cabin functions, including the headlights, daytime running lights, brake lights, parking lights, and several interior lamps. That makes position-based fitment especially important, since the correct replacement can depend on where the bulb is used and how the vehicle is equipped.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb location on your car with the chart before ordering. Some 2021 G70 models use LED assemblies that are not serviced as a simple replaceable bulb, while other positions may use a specific replaceable bulb such as the rear turn signal 7507 or the back up/reverse light 921 on applicable configurations. If you are converting from halogen to LED or buying aftermarket replacements, check whether the bulb is polarity-sensitive, whether the housing has enough space for the new bulb, and whether the car may need additional components to avoid warning messages or fast flashing. The safest step is to inspect the installed bulb before purchase and confirm the exact fitment for your trim and lighting package.
The page lists LED lighting for many positions, including the high beam headlight, low beam headlight, center high mount stop light, brake light, front turn signal, license plate light, parking light, tail light, daytime running light, vanity mirror light, glove box light, trunk or cargo area light, dome light, map light, and front and rear side marker lights. It also lists a rear turn signal bulb as 7507 and a back up/reverse light bulb as 921.
Not necessarily. Trim level, lighting package, market, and body style can change the exact fitment. Use the bulb position on the page and compare it with the bulb already installed in your car before buying replacements.
The chart shows LED for both the high beam and low beam headlight positions. On many LED-equipped vehicles, the headlight source may be part of an LED assembly rather than a traditional removable halogen bulb, so confirm the exact service method for your specific vehicle before ordering parts.
The rear turn signal light bulb is listed as 7507 on this page.
The back up/reverse light bulb is listed as 921, but only on applicable configurations. Always verify the bulb in your vehicle, since equipment can vary.
Yes, the bulb chart on this page lists both the brake light bulb and tail light bulb as LED for the 2021 Genesis G70.
You can in some cases, but fitment is not always plug-and-play. Check bulb base type, polarity, physical clearance, and whether the vehicle needs additional resistors or modules to prevent warnings or rapid flashing.
Because the same model year can have different lighting setups depending on trim or package. Checking the installed bulb is the most reliable way to confirm the exact replacement, especially for exterior lamps and any position that may be LED integrated.
Yes, interior lighting can vary as well. The page lists vanity mirror, glove box, trunk or cargo area, dome, and map light positions as LED, but you should still compare the actual lamp in your car to confirm serviceability and fit.
The page lists front and rear side marker light bulbs as LED. Depending on the specific housing, the bulb may be part of an integrated LED unit rather than a standard removable bulb, so inspect the assembly before purchasing parts.
It is useful as a starting point for the 2021 Genesis G70, but body style and market can affect lighting equipment. Use the page as a guide and verify your exact vehicle configuration before ordering.
Match the bulb location, confirm the installed bulb or housing style, and check whether your car has LED or a serviceable bulb at that position. When in doubt, compare the old bulb, the owner’s manual, and the vehicle’s lighting package before purchase.
