91538 Gas Grill Lighted Control Knobs Compatible with Weber Summit 400/600 Grills Manufactured 2012 and Later, Fit for E-470/670, S-460/470/660/670 etc.(2pcs Main Burner Lighted Control knob)

My old knobs have some hard to remove black marks, so these provide a nice update. 100% compatible. Fits snug and tight.

My Summit 600 has been going strong for over 10 years. Replacing the burners, grill & flavorizer bars is a must, but cosmetic upgrades are nice, too.The original knobs were fine, but the new ones give it a better look. My battery system fell apart long ago, so I didn't test the knob's lights, but I never use them. Probably why I haven't fixed the battery.These are very close in appearance to the original knobs, but there are slight differences. But you'd have to look closely to see the differences. They slide onto shaft and are held securely in place.Recommended if you need knew knobs, or just want a cleaner look for an older grill.

These knobs are a great replacement for the original Weber knobs. The plastic and all materials are very high quality. They fit perfectly and are nice and tight on the valve stems.These knobs are for 2012 and later grills. I actually purchased my grill in 2010 but the knobs still work great. The only difference is that the knobs on the later models rotated much more than the older versions, so the flame level marks on the knobs don’t align with the max volume on my controls. I show this in the attached video. This doesn’t bother me at all.If you are looking for replacement knobs, you won’t be disappointed with these.
