Product review (4 stars): Snap In Replacement, But Not Quite 'White'
The light is a snap-in fit for the Xtreme hood. The light just snap clips in. To remove, just remove the grease trap near the light and push the back of the light until it pops out.

Two issues:
* The Xtreme hood doesn't have enough slack wire in the hood to pull the quick connector out of the hole so you can see it to disconnect it.  You'll have to work blind by feel to locate the connector and separate it.  Ditto for reinstallation.
* The replacement light is not the 5000K bright white that came with the unit.  It's more along the line of 4000K.  Not a huge issue, but the difference is noticeable if you only replace one malfunctioning light as I did.
