The K{sup +} scattering on the lightest nuclei, d, {sup 3}He, and {sup 4}He is studied in the framework of multiple-scattering theory. Effects from meson exchange currents (MEC) tied to the K{sup +}N{r_arrow}KN{pi} reaction are evaluated. We found that at momentum transfers Q{sup 2}{lt}0.5 (GeV/c){sup 2} contributions from MEC are much smaller than kaon rescattering corrections. This makes the conventional multiple-scattering picture a reliable tool to study these reactions in this kinematical domain and to extract the K{sup +}n scattering amplitude from the K{sup +}d data. At larger transferred momentum MEC can become more relevant. {copyright} {ital 1997} {ital The American Physical Society}
