I bought a strobe set from Ripmax and they are very bright. The bulbs are U shaped and about 12 mm wide so they are difficult to place in a scale installation. They look and act like a photo flash going off. I found the electronics can't take 7 volts- the hard way :stupid: smoked the transistor. I have a new set on order. They sell for 24 Euro and would be fine for a sport jet. Still looking.
