MG 00 GN Drive LED Module - GREEN
Information from Delpi Decal's web site (edited for grammar and spelling):
MG 00 GN Drive LED Module
Contains 1 LED Module + Battery + Magnet
There is an on/off switch on the back so you can control the LED module.
If you leave the LED module switched on and take the magnet close to you, the product will work, and if you take it close again, the product will turn off.
It is also compatible with MG 00 series kits, but due to the thickness of the runner, the LED may not function properly even if the magnet is attached.
It is not possible to exchange or return due to the above reasons, so please refer to it when purchasing.
Other 00 series kits recommend using magnetic LED products that are currently on sale.
