PS! the battery can supply high power
= use fuses / switches . . .
. . . work at a suitable workplace (no foreign objects around , proper lighting , the circuit (wiring) firmly fixed or isolated by insulators , etc. )

otherwise (in case of the short) thin wires would melt (act as fuses)
also the 55W = (12V)² / 2.6Ω (hot / ? 1.3Ω cold) car light in series would limit the current in circuit below the 4.6A = 55W / 12V
