Different car lamps with different brands. For the purchase of the following suggestions: you should be clear about what brand of lights your own car.... For example. Mercedes-Benz. BMW... The lamps. And brand out of the professional lamps and lanterns technology. It's basically the same. So there's no need to spend hundreds of dollars more on the original lamps.. And Toyota.. Because KOITO did not produce the corresponding lamps. So. If you have a high demand for lights. It's better to use the original. Because in the Toyota series of lights without gas. Hardly over a thousand.... But the price will be different according to the different models, not because of the different sizes... Remember... Of course. In DEPO lamps. Lighting and other technology is also good... For general use will not be a big problem... When purchasing lamps... First look at the packaging... General. Whether it is a genuine factory. Professional factory lamps.. Paper will belong to a very good kind... (As to how to be good. This is really to feel...) It's not too soft.. It's not too hard. Then look at the surface of the lamp... Touch it with your hand. (It doesn't really work) See if it's transparent enough.. Of course it is. It's not crystal. That's a different story. It's best to tap the surface of the lamp with your hand... Generally speaking, good lamps and lanterns will produce a more solid sound... A bad lamp will make a clear sound.. Glass-fronted lamps are a different story. There are a few more problems with non-conforming lamps... The lighting problem is the most important... The lighting problem is the most important one, and it's easy to turn gray. Easy to lose color... Because of the ability and technical problems... I can't express it in detail... Because a lot of skills can not be said with the mouth... A lot depends on experience ...
