I am looking to replace the rear lights on my 2021 Hyundai Elantra SEL with LED lights, since the base incandescants are not bright enough for my needs.
Looking through the owner's manual, (Section 2 page 8) I have become quite confused at which type of bulbs I need. I am looking to replace (most of) the rear lights, and since I have the SEL trim I am under the impression my car falls under "Type A." For the stop lamp, it lists a "P21W/5W" bulb as replacement, a W5W bulb for the inner tail lamp, and a P21/5W bulb for the outer lamp. What is the difference between the P21W/5W light and the P21/5W light? Is there a difference?
I am sorry if this is a stupid question, I have never touched the lights on a car before and my expertise is almost solely in tires/wheels since that is what I do at my job. Thank you for your assistance.
(An additional little bonus question, I am unclear on what the difference is exactly betwen the tail lamp and the stop lamp. What is the difference? How many stop lamp/s are there that I would need to replace?)
