One low beam was burnt out. I went to NAPA to get a replacement. All they had was halogen sealed beams. I bought two.
My question is: do halogens use any more power than the old sealed beams? These are 35W bulbs. Will using them cause the bi-metal breakers to heat up?

I always keep spares on hand for all the different lights

Only if the wattage on the new bulbs is greater than the old ones.
Now I doubt that they are, most replacement bulbs or seal-beams are of the same wattage even though the new bulb happens to be halogen.
