        <description>I didn't even know what Grab was when I bought this.  It turns out that it may be food delivery company in Singapore, which makes it odd that it was listed on eBay UK.  It was from a seller who also had various other vehicle signs like "TAXI". It wasn't expensive, so it may have use as a novel illuminated ornament. To find it on eBay, search for the keywords "grab LED sign". The construction is pleasingly simple.  Just a bare PCB with black resist and the logo as a white screenprint.  The logo is formed by simple LED/resistor circuits like LED tape. Current draw at various voltages is:- 10V - 80mA 11V - 130mA 12V - 173mA 13V - 225mA 14V - 278mA The construction is reminiscent of some LED art panels. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. #ElectronicsCreators</description>
