Light up your device's LED no matter which app you're in by holding Search.
Switch on (and off) your device's LED by holding the Search button, no matter which application you're in.
Or if you prefer, use the Searchlight shortcut to toggle the LED instead.
To make Searchlight the default, simply hold Search, then tick the "Use by default for this action" checkbox, then select Searchlight.
If you want that Search selection to appear again, go to Settings > Applications > Manage applications > Searchlight > "Clear defaults" button. Then hold Search again and make a new selection. It will also reappear when the list of actions changes, for example you install or uninstall an app that has global search functionality.
You can even switch off the screen whilst keeping the LED on. Just note that you won't be able to toggle the LED with the screen off — switch the screen on, unlock it if necessary, then hold Search.
Searchlight uses a Service to keep the LED on whilst switched off. You can kill it if you like, but you don't have to — it'll close itself when the LED is switched off.
• Only supports devices that implement the standard flash interface. If it doesn't work on your device, drop me an e-mail and I'll see if I can get it working.
• Don't open any application that uses the camera while Searchlight is on, such as Camera, Barcode Scanner, Shopper, etc. They probably won't work — just hold the Search button to switch off Searchlight, and re-open the broken app. I'll try and fix this if it's possible to.
• As above, don't open Searchlight whilst using an app that's using the camera. I can't guarantee what might happen!
Searchlight uses the camera's flash to light up the LED.
Searchlight needs wake lock. Without it when the screen gets switched off, the LED would also switch off.
