The OTC 3630-10 are actually 1.5 Volt bulbs...NOT a 12 VOLT Bulb! NOT 12 Watt either. NO where in this Listing does it state the Voltage...Only 12 WATTS...and That is False as well! Using Ohms Law, 12 Watts divided by 1.2 Volts = 8 AMPS. (Watts = V x A) Probably 50mA is more accurate when powered by a 1.5V size AAA Battery, which they are meant for use in a OTC 3630 "Continuity Tester", which You can find on Amazon for $34.95...and is the Only correct application for these Bulbs. But, all Multimeters have a 'Continuity Test' function, so there is no use for Buying a 'Continuity Tester' or these bulbs!

As a mechanic we all make mistakes from time to time. They should include more bulbs.

Bought these after searching 12 v test light bulb received pack pulled out a bulb, put in 3633 OTC test light and attached to 12V power source and bulb blew instantly. check the package and it clearly states 1.5 v it would have been nice if the amazon listing had said that, not just 12watts.

12 watt advertised no voltage, come to find out upon delivery 1.5 volts 12 watts. Does nothing for my 12 volt test light, after the 4.95 return shipping stuck with a worthless product!

J'ai attendu presque 2 ans que le prix soit inférieur au prix du testeur entier... Éclair faiblement, faut être attentif. Il y a des testeurs beaucoup mieux sur le marché, je n'utilise plus ce OTC
