Depends where you put it !! The blue LED bulb don't say on the package this is DOT approved for lic plate bulb...does it ?? That 197 bulb fits in a lot of places in your truck.

If it was true that you have to have DOT white lights I wouldn't see ppl everyday with blue led in the license plate

Why are you guys rating these bulbs by K(Kalvin). leds light out put is measured by Lumens. If you want a blue LED that is not going to be purple looking you need a High Lumen LED. 90 lumen +
