Default Discharger/Equilizer Bulb Amp Rating

Does anyone know the amperage rating on the bulbs that are typically used on discharger/equilizer Trays?

Well, I don't have an exact number, but my understanding is that GE 1157 bulbs draw 2 amps per bulb, so if you use 10 bulbs in a discharger with them, you should have a 20 amp load. But for trays, many don't actually rely on the bulbs for the discharge load, they use resistors to put a load on the cells. Since those bulbs are smaller, they should draw considerably less than an 1157 bulb, but I wouldn't even hazard a guess at what they'd draw on their own....

Iam sorry I wasnt clear on what I was doing. Iam getting an equilizer tray off a guy but its missing some bulbs, so i was looking to replace them. Ya i know about the resistors, i guess the bulbs are just used to show the status of the cells right? the amp rating doesnt really matter?

Pretty much, yeah. Maybe the best thing to do is take one of those bulbs to an automotive parts shop & see if they can help you identify them....
