In this letter, I would like to explain to you 193 vs 168 bulb as below.

Auto bulb 193 and 168 almost same.

Because 193 and 168 bulb are 12v and “W2,1*9.5d”.

168 bulb is litter bit higher watts than 193 bulb.

For example, 168 bulb is 12v 4.9w, but 193 bub is 12v 4.62w.

All of 193 and 168 bulb can be replaced by led.
