Ubuntu You can also buy two, for example, if you use G90N bulbs at home to connect everything easily, and use them on the vehicle's roof rack without having to constantly adjust and disassemble.
I initially bought the 891, but I couldn't get a license for it. So I bought a G90N to use with the license. Later, the 891 became eligible for licensing, and I wanted to sell the G90N, but then I thought it was too much trouble, so I didn't sell it. However, I found that the G90N was still useful at home, so I decided not to sell it.
