If you thought the kit’s flashing lights and siren were a bit to fast for a realistic Euro Police Vehicle you were right. As Ren and son Ansel pointed out, you always have to Read The Instructions. Guess I didn’t. Had I, I would have noticed that they directed me to remove two resistors I so carefully soldered in place, and to replace them with two resistors twice their values. This in turn doubled the RC time constants controlling the flash rate, effectively cutting it in half. See and hear for yourself.
